if a ball of mass, m is travelling at v and it hits a stationary ball that is a much larger mass (ignoring air resistance, friction etc.) through algebra how would you show that when the mass of the stationary ball decreases slightly, the total kinetic energy that the stationary ball gains after the collision increases. (it is assumed that it is an elastic collision ie. kinetic energy is conserved)
