1. A 0.750 kg hollow sphere with a diameter of 25 cm diameter starts from rest at the top of a 65 cm tall incline. There is just enough friction on the incline to make the sphere roll instead of slide.

(a) What types of energy does the sphere have at the top? at the bottom?

(b) What is the moment of inertia of the sphere?

(c) What is the velocity of the sphere when it reaches the bottom of the incline?

(d) Would a solid sphere of the same mass and size reach the bottom of the incline before or after the hollow sphere?
