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=3.1νν. initially ν"is on the ground and ν#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ν#just before it strikes the ground. assume the pulley bearing is frictionless.
