Two masses, mA = 35.0 kg and mB = 38.0 kg, are connected by a rope that hangs over a pulley. The pulley is a uniform cylinder of radius 0.381 m and mass 3.1 kg. Initially mA is on the ground and m2is 2.5 above the ground. If the system is released, use conservation of energy to determine the speed of mB just before it hits the ground. Assume the pulley is frictionless.
