## Under less than ideal conditions, a student pushes a 6kg cart holding 2 boxes of books up a ramp to a platform that is 1.8m high in 42 seconds.

Each box contains 12kg of books. The ramp is inclined at an angle of 15 degrees. He pushes with a steady 84N to move it up the ramp.

So:
Work input = 84N
Power = 2J

What is the work output and how do I find it?
