Question

If the following three objects are released from the same initial height and allowed to roll down a ramp, predict the ranking of their speeds at the bottom of the ramp (from fastest to slowest). (Assume the objects have the same mass and radius. Use the following as necessary: C, D, and S for the speed of the hollow cylinder, solid disk, and solid sphere, respectively. Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.) Explain your reasoning for your prediction. A.) Objects with a larger k value will have higher speeds at the bottom of the ramp. B.) Objects with a smaller k value will have higher speeds at the bottom of the ramp. C.) All three objects will have the same speed at the bottom of the ramp.
