A 55-kg packing crate is pulled with constant speed across a rough floor with a rope that is at an angle of 41.0 ∘ above the horizontal.

If the tension in the rope is 195 N , how much work is done on the crate by the rope to move it 3.0 mm ?

2 answers

Force in direction of motion = Fx = 195 cos 41

so work done = 195 cos 41 * 3 Joules
I assume you mean 3 meters, not 3 millimeters
