Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ķ
=0.381meters and mass ķ=3.1ķķ. initially ķ"is on the ground and ķ#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ķ#just before it strikes the ground. assume the pulley bearing is frictionless.
