Assume that the coefficient of kinetic friction between the concrete block and the wall is 0.88. A 2.5-kg concrete block sliding on a vertical wall is being acted upon by a force P as 148° (a) Draw the free-body diagram of the concrete block. (b) If the normal force exerted by the wall to the concrete block is 20.0N, what would be the magnitude of the external force P, and (Ans: 37.74 N) (c) The acceleration of the block? (Ans: -15.56 m/s) ミ
