A small cart carrying a small physics student (total
mass = M) is designed to coast into the wall (at speed vi) and bounce off traveling in the opposite direction (at speed vf). In doing so, the wall must deliver an impulse to the cart. Which of the following suggestions would increase the magnitude of the impulse delivered by the wall. All nonspecified variables (vi, vf, and M) remain constant unless the stated conditions imply some change. For each statement select either Yes or No.
1.Make the cart experience a greater change in momentum.
2.Decrease the total mass of the cart and rider.
3.Increase the force and time of contact with the wall.
4.Decrease vf.
5.Have the person stand up in the cart.
6.Design the cart with a new bumper so contact time is increased.
my answers are:
Yes
No
Yes
No
No
Yes
Some of them are wrong, but I dont know which one, can anyone help me with it?
