Question

A solid sphere and a hollow cylinder of the same mass and radius have a rolling race down an incline. They start at rest on an incline at a height above a horizontal plane. The race then continues along the horizontal plane. The coefficient of rolling friction between each rolling object and the surface is the same. Which object rolls the farthest? (Justify your answer with an algebraic expression.)

Answer 1

Answer:

A solid sphere will roll the farthest because it is smaller than cylinder and in smaller objects friction is very less than large objects.

Answer 2

Answer:

Hollow cylinder will move faster than solid sphere

Explanation:

moment of inertia is more for hollow cylinder
