Two masses, m1 = 27.0 kg and m2 = 50.0 kg, are connected by a rope that hangs over a pulley (as in fig. 10-60). the pulley is a uniform cylinder of radius 0.40 m and mass 4.8 kg. initially m1 is on the ground and m2 rests 2.5 m above the ground. if the system is released, use conservation of energy to determine the speed of m2 just before it strikes the ground. assume the pulley bearing is frictionless.
