it reaches the bottom of the incline?

Answer #1

Thank You.

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.
