Two objects each moving with speed v travel in opposite directions along a straight line passing through both their centers. the objects stick together when they collide and move together with speed v/4 after the collision.
(a) what is the ratio of the final kinetic energy to the initial kinetic energy? ( kf/ki = 1/16)
(b) what is the ratio of the mass of the more massive object to the mass of the less massive object? ( mmore massive/mless massive = 5/3)
