Question
The drawing shows two boxes resting on frictionless ramps. One box is relatively light and sits on a steep ramp. The other box is
heavier and rests on a ramp that is less steep. The boxes are released from rest at A and allowed to slide down the ramps. The two
boxes have masses of 13 and 37 kg. If A and B are 4.5 and 1.0 m, respectively, above the ground, determine the speed of (a) the
lighter box and (b) the heavier box when each reaches B. (c) What is the ratio of the kinetic energy of the heavier box to that of the
lighter box at B?
