P Problem 6/21 22 The system of two blocks, cable, and fixed pulley is initially at rest. Determine the horizontal force P necessary to cause motion when (a) P is applied to the 5-kg block and (b) P is applied to the 10-kg block. Determine the corresponding tension T in the cable for each case. 6/24 Determ 100-lb have ne P(a) 5 kg =0.50 10kg P(b) P=0.30 =0.25 Problem 6/22 H=0.60
