In the figure below, three ballot boxes are connected by cords, one of which wraps over a pulley having negligible friction on its axle and negligible mass masses are ma = 22.0 kg, me = 41.0 kg, mc = 16.0 kg. (a) When the assembly is released from rest, what is the tension in the cord connecting B and C? (b) How far does box A move in the first 0.250 s (assuming it does not reach the pulley)? In the figure below, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude 73 = 70.8 N. T3 (a) If m1 = 11.5 kg, m2 = 23.5 kg, and m3 = 30.5 kg, calculate the magnitude of the acceleration of the system. (b) Calculate the tension 71. (c) Calculate the tension 72.
