3. (20 pts) A block of weight, W = 50.N, is in contact with a vertical wall at a height, H = 4m, above the ground. The coefficients of static and kinetic friction between the block and the wall are 4, = .4 and UW, = .2 respectively. You apply a force F = 2W at 0 = 45° as shown. FE 777 a) Find the direction of the friction force between the block and the wall. Justify your answer. b) How high is the block above the ground after lime, t = 2 sec. Justify your answer.
