Two masses, mA = 34.0 kg and mB = 38.0 kg , are connected by a rope that hangs over a pulley (as in the figure). The pulley is a uniform cylinder of radius 0.381 m and mass 3.1 kg. Initially mA is on the ground and mB rests 2.4 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.
