Engineering Mechanics - Dynamics Chapter 15 Problem 15-25 Determine the velocities of blocks A and B at time t after they are released from rest. Neglect the mass of the pulleys and cables. Given: W A 2lb = W B 4lb = t 2s = g 32.2 ft s 2 = Solution: 2 s A 2 s B + L = v A v B = Block A 02 TW A () t + W A g v A = Block B B t + W B g v A = Combining W B W A t W B W A + g v A = v A W B W A W B W A + gt = v B v A = v A v B 21.47 21.47 ft s = Problem 15-26 The package of mass M is released from rest at
