All live ramps have the same height, ramps B. C. D and E have the same length, ramp A Is longer than the other four. You need to push a heavy cart up to the second floor and you may choose any one of the five ramps. What is the kinetic energy of the rock just before it hits the ground 1. Ky - mgh 2.
