In Figure 5-50, three ballot boxes are connected by cords, one of which wraps over a pulley having negligible friction on its axle and negligible mass. The masses are mA = 22.0 kg, mB = 40.0 kg, mC = 18.0 kg.

(a) When the assembly is released from rest, what is the tension in the cord that connects boxes B and C?
N
(b) How far does box A move in the first 0.250 s (assuming it does not reach the pulley)?
m
and the other is
Figure 5-55 shows three blocks attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table; the masses are mA = 7.00 kg, mB = 8.00 kg, mC = 10.5 kg. When the blocks are released, what is the tension in the cord at the right?
