A frictionless pulley has the shape of a uniform solid disk of
mass 2.90 kg and radius 10 cm. A
1.50 kg stone is attached to a very light wire that is
wrapped around the rim of the pulley (the figure (Figure 1)),
and the system is released from rest.

Part A: How far must the stone fall so that the pulley has
5.30 JJ of kinetic energy?
Part B: What percent of the total kinetic energy does the
pulley have?
