Question: In the system shown in Fig. 9.18, a 12.O-kg mass is released from rest and falls, causing the uniform 1O.0-kg cylinder of diameter 30.0 cm

In the system shown in Fig. 9.18, a 12.O-kg mass is released from rest and falls, causing the uniform 1O.0-kg cylinder of diameter 30.0 cm to turn about a frictionless axle through its center. How far will the mass have to descend to give the cylinder 250 J of kinetic energy?
