Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ํ
=0.381meters and mass ํ=3.1ํํ. initially ํ"is on the ground and ํ#rests 2.5 meters 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.
