A 50-kg crate is pulled 40 m along a horizontal floor by a constant force exerted by a person. The applied force is 100 N, which acts at a 37 degree angle wrt the horizontal. The floor is rough and exerts a frictional force of 50 N. a. Determine the work done by each force acting on the crate. b. Determine the net work done on the crate. correct answersa. -work done by the person - WF = F * x * cos(theta) WF = 100 * 40 * cos(37) WF = 3194.54 J the work done by the applied force is 31...
