(II) Two masses, mA = 35.0 kg and mB = 38.0 kg, are connected by a rope that hangs over a pulley (as in Fig. 10-59). 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 2.5 m above the ground. If the system is released, use conservation of energy to deter- mine the speed of mB just before it strikes the ground. Assume the pulley bearing is frictionless. %3D RO mB mA 2.5 m FIGURE 10-59 ba Problem 67. inoni lo (IID) A.
