Question

Two masses, mA = 35.0 kg and mB = 42.0 kg, are connected by a rope that hangs over a pulley (as in the figure). The pulley is a uniform cylinder of radius 0.50 m and mass 4.8 kg. Initially mA is on the ground and mB 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.
