A solid sphere with a radius 0.25 m and mass 240 g rolls without slipping down an incline, starting from rest from a height 1.0 m.

a. What is the speed of the sphere when it reaches the bottom of the incline?

b. From what height must a solid disk with the same mass and radius be released from rest to have the same velocity at the bottom? It also rolls without slipping.
