A solid ball and a hollow ball with the same mass M and radius R are both released from rest at the top of a ramp of height h. Which, if either, will be traveling faster at the bottom? Explain your reasoning. The moment of inertia of a solid ball is 2/5MR2 , and the moment of inertia of a hollow ball is 2/3MR2 .
