In Fig. 6-50, block A of mass 2.0 kg, block B of 3.0kg, and block Cof 6.0 kg are connected by strings of negligible mass that run over pulleys of negligible mass and friction. The coef ficient of kinetic friction between block B and the table top is 0.40. When the system is released, the blocks move. What is the magnitude of their acceleration?
