A block and a sphere released from rest at height h.
A block and a sphere released from rest at height h.
A block of mass \(M\) and a solid sphere of mass \(M\) are both released from rest at the same height \(h\) on two different ramps. The block slides down a frictionless ramp, while the sphere rolls without slipping down a second ramp that has significant static friction. Both objects reach the bottom of their respective ramps. Which of the following correctly compares the translational speed of the block \(v_{\text{block}}\) to the translational speed of the sphere \(v_{\text{sphere}}\) at the bottom of the ramps and provides a correct justification?
