Problem
A hoop and a solid cylinder have the same mass and radius. They both roll, without slipping, on a horizontal surface. If their kinetic energies are equal,
(a) the hoop has a greater translational speed than the cylinder;
(b) the cylinder has a greater translational speed than the hoop;
(c) the hoop and the cylinder have the same translational speed;
(d) the hoop has a greater rotational speed than the cylinder.
