Question: A sled of mass m is being pulled horizontally by a constant horizontal force of magnitude F. The coefficient of kinetic friction is Îk. During time interval t, the sled moves a distance s, starting from rest.
Part A: Find the average power Pavg created by the force F.
Express your answer in terms of the given quantities and, if necessary, appropriate constants. You may or may not use all of the given quantities.
