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