Two masses, mA = 34.0 kg and mB = 40.0 kg , are connected by a rope that hangs over a pulley (as in the figure (Figure 1)). The center of the pulley is hollowed out so that you may assume all the mass of the pulley is in the rim. The radius of the pulley is 0.381 m and the mass of the pulley is 3.10 kg . Initially mA is on the ground and mB rests 2.50 m...

Initially Ma is on the ground and Mb rests 2.3m above the ground. If the system is released, use conservation of energy to determine the speed of just before it strikes the ground. Assume the pulley bearing is frictionless.
