The drawing shows two boxes resting on frictionless ramps.Onebox is relatively light and sits on a steep ramp. The other boxisheavier and rests on a ramp that is less steep. The boxesarereleased from rest at A and allowed to slide down the ramps.Thetwo boxes have masses of 14 and 32 kg. If A and B are6.0 and 1.0m, respectively, above the ground,determine the speed of(a) the lighter box and(b) theheavier box when each reaches B.(c) What is theratio of the kinetic energy of theheavier box to that of thelighter box at B?
