The two ramps pictured here each have a region of length L with kinetic friction coefficient uk and are otherwise frictionless. Identical masses m start at identical heights up the ramps, with the same initial velocity down the ramp. How do their final speeds compare when they reach the far right-hand side? (The answer requested here is qualitative and does not require detailed calculation).
