Hint 1 A ramp of mass M = 7 kg is at rest on a horizontal surface. A small cart of mass m = 1.25 kg is placed at the top of the ramp (at a height h = 2.25 m) and released. What are the velocities of the ramp and the cart relative to the ground at the instant the cart leaves the ramp? Before release M O O Vramp After release V cart M m O O Image Description Vc n/s Vr m/s
