Problem 10. A 5 kg block is pushed 3 m up a wall by a 90 N force F1. Assume that the block starts from rest and that it has

an acceleration of 0.5 m/s?. Use 0 = 55°. (a) Determine the coefficient of kinetic friction between the block and the wall. (b) Find the work done by each force acting on the block. (c) Use the Work Energy Theorem to determine the speed of the block after it has moved those 3 m.
