Can someone actually ANSWER the question pleas and post numerical answers.

Under less than ideal conditions, a student pushes a 6 kg cart holding 2 boxes of books up a ramp to a platform that is 1.8 m high in 42 sec. Each box contains 12 kg of books. The ramp is inclined at an angle of 15 degrees. He pushes w/ a steady force of 70 N to move it up.

Find: -Work in

-Work out

-IMA

-AMA

-Efficiency

-Power
