Physics Again idk if i got the problem right. - Help.com

well sir
you have to remember the SI units of acceleration
it is distance unit/(time unit)^2

your answer is in km/second..
should be second^2

I’m a girl. so is 175000 km/s^2 right? i forgot acceleration is squared, right?

oops im so sorry
miss

well the way to do this is use the formula
v^2 = u^2 - 2*a*s

you know v = 3.5 km/sec change that to centimeter/sec
u= 0 since initial velocity is zero

s = distance = 2cm

oh initial velocity is zero. so… 350000 cm/s?

yup :)

[sorry about addressing “sir”
really feel so stupid]

let me solve it for you.. and we’ll match answers!

thats ok lol just call me miss. you just can’t assume that girls can’t be smart! ok watch me get a totally different answer this time.

haha.. it’s been sometime iv done newtonian physics.. im stuck with thermodynamics for atleast one more semester >.
so miss
do you think the velocity give is the final velocity(v) or the initial velocity (u)
i think its the final velocity
i kinda think it makes more sense

i think the initial velocity is zero and the 350000 cm/s is the final velocity. we do final velocity as (vf) and initial velocity as (vi). well its like that in my physics book and our teacher goes along with the book. I’m a high school girl. a senior. my last year. idk why I’m telling you this just fyi i guess.

well you got it right now :)
just wanted to clarify it because i got confused when you wrote

“oh initial velocity is zero. so… 350000 cm/s?”

oh your a senior.. where you planning to go for college, if you don’t mind me asking :)

there are 3 equations in my book that i think will work, but 2 of them involve time so i think this one will work: (vf)^2 = (vi)^2 + 2ad a is acceleration and d is distance.

idk. i just don’t want to take English in college. I hate English. so much. hate it. lol

yup the equation i wrote is the third equation of newton
which is the one you wrote above :)
ouch thats a lot of hate..
well got to break it to you, but any school you get into the first year you will have to take an english composition class lol =(
where do you plan to go?? must have started applying to colleges by now right?

no. idk what I’m going to do. maybe i can die before college. been really depressed lately. trying to use school work to keep my mind busy. i don’t talk in class. i don’t talk ever cuz I’m so depressed. trying to find my place in this world. don’t know who i am anymore.

Wow, sorry to hear that. You should definitely seek out some help if you’re thinking of dying that soon.

Anyway, did you want to talk about it?

you want to talk to us miss??

no. I’ve already closed up. just gonna remain a mute and do my work. doesn’t hurt as much that way.

it’s never late to open up and share with us why you are depressed..
living with that hurt makes you strong, but that’s now how you should live your life!
there are a lot of people here who can give you extremely helpful advice
and you’ll never know that until you try
make a new post and see the amount of people here who are willing to help you out :)

so…350000 cm/s = 0 cm/s + 2a(2.0 cm) just got to do the equation to where a = something

yes miss you got it… a= 350000/4
so whats your favorite song?? sorry if that’s a random question >.>

I wish I could lie and say that’s it all going to be ok. But it’s not. That is, not until you try and do something about how you’re feeling. I hope you have a good night, and find a way of your trying times.

idk what my fav song is.

really miss.. hmm okay..
how about
what was the last song you liked?

idk

okay..
how about.. hows the weather in your area looking??
it’s getting really cold down here in chicago =(

idk…i think its cold.

Do you like the cold? Hate it? Is there anything that you like?

i hate cold. idk. can’t find my passion. don’t know what i like.

Well, I’m the same way. I am currently in college and don’t know where I’m heading in life. On the bright side, you’re not alone.

hey i’m in college too! and lost lol

good…but i still am keeping everything closed up inside. i never talk. only say few words each day if that.

so in a way i am alone

well we are just wanting to talk to you miss..
just want to know you better :)

hows your studies going??
since your studying much more

I know how you feel. I’ve been talking less and less. I feel like people are not very concerned about what I have to say, so what’s the point, right? Yeah… I use to be pretty optimistic but it’s not getting any better as the days roll by.

hows your college going,uhm the other anonymous

It’s going. I’ve been obsessing about grades a bit much, though. I mean, there should never be reason to cry about get a 94% on a midterm. But yeah, buying time until I have to face the real world.

94% thats awesome lol .

>_ it’s ok.

I wonder what the original poster is up to.

I feel like I relate to her somehow.

fine, you want me to tell you how i feel? why would you want to know me? i don’t even know me. well, 1. I’m failing Trigonometry. 2. my family never gets along with each other. lots of drama and sometimes i wish when they fight they would just shut up. and my parents are divorced so i always get the story twice, but from different points of views. 3. the guy i liked that likes to be called jack by just his friends doesn’t like me anymore cuz he likes someone else and now he won’t let me call him by his real name john and i miss calling him john, but now he says to call him jack. 4. i just want to cry all the time. 5. I’m not sure what all my problems are…I’m just never happy. 6. I’m better off alone anyway.

1. You seem smart. Why are you failing Trig? Do you just not get it?
2. I don’t even talk to my family. Divorce happens. Let your parents know that you don’t appreciate the drama. Or you can just tell them to shut up when they start blabbing. Try it, it will feel very liberating even if you get a solid fist to the jaw.
4. Jack is an idiot. Not worth your time or your tears. What kind of petty stuff is that name thing anyway?
5. It sounds like you have a very good start on some of your problems. The Parents, the Jack, the Trig, you just need to figure out what to do about them.

Sahaven,

What’s your major?

miss
1. i think your smart enough for trignmtry, it’s the environment your in that’s making you not to study
2. yes i do want to talk to you
3. the boy you liked doesn’t like you anymore, and so you must move on… i know it’s the hardest thing in the world. to try and move on, but you have to.. there is someone out there better than him who will love you more than his life.. don’t get stuck on a person who does not like you..
4. as for your family, in real almost all families have some issues that goes on between them.. you have to be strong about that miss

5. i can’t personally type your tears off, BUT
*magically a box of tissues appears in front of you*

My numbering is way off but my intent was pure.

engineering ..
doing Industrial for now, might minor in mechanical if i need it (i’ll get to know better after an internship next summer lol )

how about yourself.. also like you said ..lets get back to the main poster

1. ya, i could do it if i had better environment
2. jack is an idiot, but i don’t want to talk to him anymore cuz he broke my heart, but I’ll always remember him as john whether he likes it or not.
3. love how the magic box of tissues appeared. now got anything to make my head stop hurting?

Lol, for that I’ll offer you some alker seltzer things.

It sounds like you’re moving in a good direction :D

doesn’t feel like it.

Trust me, you’re far cry away from the person I was responding to an hour ago. You’ve opened up a bit and I’m glad for it!

well miss let’s talk about your future then
be honest.. and we might just be able to comfort and give you hope :)

you wanna get away from home? so i suggest college is really a must.. change of environment
for your head.. well drink some water firstly … usually warm water is best and do some deep breathing

also any close friends??

a couple close friends, but they will be gone after graduation. yes, i want to get away. idk what i want to do. i would fail English in college just like I’m failing Trig there would be too much pressure. that and i suck at english anyway i’d rather not go to college to avoid it. i don’t like english. i don’t really like anything. just want to die.

English isn’t that bad! Shoot, if I had to confess how bad I am at math, I’d probably be forced to tears. So then, you haven’t applied? You should really look into it! What’s the worst that could happen? Denial? Well, you’re not expecting much at the moment so it’s at least worth a shot.

i don’t want to apply. i don’t want to take English. I would fail. I’m done with English…DONE!!!

hey hey cmon miss
there is probably only one english class your gonna have to take in your four years in college..so don’t even worry about that
you’ll be spending more time on the subjects that you want to take :)

i’v actually come here from the other side of the world.. my family is still there ( i am a resident here now though)
and i know that it is sometimes difficult to make friends in new places.. but trust me, get into a good college and you’ll enjoy it
and meet people everyday! (there are like 40,000 kids here lol )
and how will dying help at all? you’ll be gone, you won’t be enjoy your time with your soulmate who is going to meet you soon..
and you might miss my magic tricks too lol :)

there won’t be a soulmate for me b/c i won’t open up to him.

you will be then as you are right now
don’t give up yet miss

well he’d have to promise not to break my heart.

You should first try to understand and accept yourself before you think about soulmates. Don’t even think about it. In time, it will all fall in place(kind of).

For the moment, hang out with those friends of yours! Are you they generally depressed as well?

somethings are implicitly understood.. but im sure he will promise you that if you would too :)

no they are not depressed.

whats implicitly?

Hearts are meant to be broken. I’ve had mine trashed about one or twice and I’m better for it. Not to mention, that I’ve done my fair share of heartbreaking as well. Don’t be so afraid of getting hurt. It’s pertinent to living a life. What would the winter be like if there was no summer? What would love be like if you didn’t know how to hurt like hell?

feelings or words that are understood without you saying them :)
explicitly is the other way around

ok

Have a good night, miss. I hope you find that a pleasant day awaits once you’ve shed your slumber. =)

what kinda hobbies do you like?
and cmon, there must be some song you like?

idk…i don’t really like one certain song i like different songs different artists that i like. i don’t really do much.

i like avril lavigne and taylor swift and daughtry and nickelback and pink and idk

oh i love nickelback and taylor swift too!
see miss that wasn’t too hard..
and we found something in common too!
daughtry.. there was this one song by them that i really loved.. can’t remember it.. hmm

what songs you like by them?

gonna change into my pjs now…my adorable Thumper pj pants…don’t laugh.

the new one by nickelback i can’t remember what its called and the one where live each moment like your last. and you belong with me. oh and i like that doll song i can’t remember what its called. I’m not a doll this ain’t a doll house.

cute pjs :)
seems like you don’t listen to them a lot huh?
but im glad that you like some sons atleast

let’s see .. have you heard “fireflies” b y Owl City?
it’s a really cute song.. you might just like it ^^

oh that fireflies song? that song is weird. weird, but i like it.

hahaa
thats good
how about life house? theres this song called “everything” by them.

so now you gonna tell me what you like doing during your free time?

i think i heard a song by them i liked, but i can’t remember what it was called. i don’t really do much in my free time.

ok you don’t do much.. but you do something right??
what do you like doing??
maybe reading a book? play an instrument? write in a diary? poems? sports? running?

i waste my time doing nothing. i stay on the computer playing games. watch tv. read books. and I’m trying to learn how to play on the keyboard…so far i’ve got twinkle twinkle little star down pretty good lol

hahaa
thats nice :)

am i keeping you up ?? do you have school tomorrow or something?

your not keeping me up, but i do have school tomorrow. i’m still up doing my homework.

oh ok..
need some more help… i’ll be able to help with your math/science stuff only though lol

oh well after i finish my Spanish i have trig and physics still.

haha finished my Spanish homework.

nice miss!
so are you feeling lil better?

ya

aight!
so open a youtube window
and listen to uhm..
hmm i still don’t exactly what kind of music will help.. but
do you like red hot chilli peppers?

idk.

aww miss you really can’t go back to saying “idk” !!
ok im running dry of questions lol

so you mentioned you liked video games
which ones??

i play burnout on my xbox

oh thats an awesome game..
i used to love playing burnout 4 .. some fun times playing that game :)

oh no…freakin trig…got lots of problems and its late go to bed now and i get 5 hours of sleep.

well im here..
i should probably be able to help you go through it pretty fast :P
so shoot any questions you have

i beat burnout revenge on my xbox still gotta beat the burnout paradise though. hate the song at the beggining of that game

a good song is until the end by breaking benjamin

burnout is a cool game, i like playing dawn of war online

ok, trig find all solutions of the equation in the interval [0,2pie) lol i cant type the symbol for pie. cos^3x=cosx

oh i havent heard of that song..

imma check that out..

so far i’ve got
cos^3 = cosx
cos^3 - cosx = 0
cos^2 = 0

idk what i do next

oh i learnt trig as (im a year 10 doing math b preperation)

find the sides (hypotenuse, adjacent and opposite)

then there are 3 ways to do it (more like 6 but ill just focus on these 3

it could be a tan, sin or cos:

for Tan its tanX^(degrees)=opp over ADJ

for sin its sinX^= opposite over hypotenuse

for cos its cosX^= adj over hypotenuse

uhm
is the answer
just ‘0′? (zero)

ya, soh-cah-toa. sin=opp/hyp cos=adj/hyp tan=opp/adj

no, its suppose to be something + 2pie(n) or pie(n)

no, x=o x=pie/2 x=pie x=3pie/2

well for that equation
cosine is zero between at pi/2,3pi/2 and so on

so between the interval [0,2pi)
it’ll just be pi/2 and 3pi/2

oh ya
forgot the zero too
nice job!

i forgot odd answers are in the back of the book

and crap i have to go to bed, maybe my tutoring teacher can help me tomorrow

4 hours of sleep for me. YEY!

well atleast your cheerful now miss!!
gnite then!

and come back and say hi sometimes!

ok, but I’ll need more sleep next time.

haha i won’t talk tooo much
gnite!

gnite
