a man applies a force of 220 N horizontally to the right against a 50 kg crate. the force of friction between the crate and the floor is 200 N. if the crate is pushed 2.0 m, the work done is....
What formula would be applicable?

Applied force x distance moved = Work done

Work done = 220 * 2.0 = 440 J

The mass and friction force do not matter when computing work, but they do influence the acceleration rate.
