a dock worker moves a shopping crate with a mass of 75.0 kg from one location to another 500.0m away by pulling a rope attached to the crate. The worker applies a force of 1500N to the rope, which makes an angle of 45 degrees with the horizontal. If the coefficient of kinetic friction between the crate and the ground is 0.38, what is the net work done on the crate?
