Friction

In Fig. 5-52, three ballot boxes are connected by cords, one of which wraps over a pulley having negligible friction on its axle and negligible mass. The three masses are mA = 30.0 kg, mB = 40.0 kg, and mc= 10.0 kg. When the assembly is released from rest, (a) what is the tension in the cord connecting B and C, and (b) how far does .A move in the first 0.250 s (assuming it does not reach the pulley)?
