Two objects moving with a speed v travel in opposite directions in a straight line. The objects stick together when they collide, and move with a speed of v/10 after the collision.

(a) What is the ratio of the final kinetic energy of the system to the initial kinetic energy?
1/100 [Your answer is correct.]

(b) What is the ratio of the mass of the more massive object to the mass of the less massive object?
