(A) A sled of mass m is being pulled horizontally by a constant horizontal force of magnitude F. The coefficient of kinetic friction is mu_k. During time interval t, the sled moves a distance s, starting from rest. 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.
(B) A sled is being pulled along a horizontal surface by a force vector F of magnitude 600 N. The force makes an angle of 60 with the direction of the sled's velocity. Starting from rest, the sled speeds up with acceleration 0.08 m/s^2 for 1 minute. Find the instantaneous power P created by the normal force at t=10 s. The magnitude of the acceleration due to gravity is g=9.8 m/s^2. Express your answer in watts to three significant figures.
