A solid cylinder and a thin-walled hollow hoop of equal mass \(M\) and equal outer radius \(R\) are released simultaneously from rest at the top of an incline of height \(h\). Both objects roll down the incline to the bottom without slipping. Which object converts a greater fraction of its initial gravitational potential energy into rotational kinetic energy, and which object reaches the bottom of the incline with the greater translational speed?
