A frictionless pulley has the shape of a uniform solid cylinder of mass 2.50 kg and radius 20.0 cm. A 1.50-kg stone is attached to a very light wire that is wrapped around the rim of the pulley and the system is released from rest. (a) What is the velocity of the stone after falling 2 m. (b) What percent of the total kinetic energy does the pulley have?
