Two objects, A and B, are both released from rest at the same time from the top of a ramp. Object A is a solid cylinder, and Object B is a hollow cylinder. Assume that both objects roll without slipping down the ramp. The mass, the radius, and the moment of inertia of both objects are found in the table below.
