Two masses, mA = 32.0 kg and mB = 38.0 kg, are connected by a rope that hangs over a pulley (as in the figure below). The pulley is a uniform cylinder of radius R = 0.311 m and mass M = 3.1 kg. Initially, MA is on the ground and mg rests 2.5 m above the ground. If the system is released, use conservation of energy to determine the speed of mB just before it strikes the ground. Assume the pulley bearing is frictionless.
