A 12.5 kg block 1s pushed across a rough horizontal surface by a 75.0 N force inclined to the horizontal at 30 (see diagram below). The coefficient of friction between the block and horizontal surface 1s p = 0.35. Draw, in the space provided below, a free-body diagram showing all the forces acting on the block. 3N The normal force exerted by the surface on the block 1s The acceleration of the block 1s Suppose that the configuration 1s now changed and the block 1s pulled by the 75 N force inclined at 30" to horizontal as shown below The acceleration of the block would now be = e 11 = 75N
