a hoop is rolling (without slipping) on a horizontal surface so it has two types of kinetic energy: translational kinetic energy and rotational kinetic energy. the entire mass m of the hoop is concentrated at its rim, so its moment of inertia is i = mr2, where r is the radius. what is the ratio of the translational kinetic energy to the rotational kinetic energy?
