3. A hoop and a solid sphere are released from the top of a ramp at the same time. The objects have the same radius, but the mass of the sphere is 5M, while the hoop is M. The moment of inertia for the sphere is 2/5MR? and the hoop is MR?. a. Which object, if either, will reach the end of the ramp first? Explain your answer. b. Which object, if either, will have a greater rotational kinetic energy at the bottom of the ramp? Explain your answer.
