Example 6 A frictionless pulley has the shape of a uniform solid disk of mass 2.50 kg and diameter 40.0 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. How far must the stone fall so that the pulley has [4.50 J of kinetic energy?
