A person pulls a 50 kg crate 40 m along a horizontal floor by a constant force of 100 N, which acts at a 37° angle. The floor is rough and exerts a friction force 50 N. Find (a) the work done by each force acting on the crate and (b) the net work done on the crate.

Verified answer
Formula = force X distance X cosine(y) if cosine is parallel to movement
Net work= 2000X cosine 37 joules
Work due to friction = -2000X cosine 37
Joules
Work due to box= 4000X cosine 37 joules
