A truck drives to a rock quarry at a speed of 20 m/s. The truck takes on a load of rocks, which doubles its mass, and leaves at the same speed of 20 m/s. Quantitatively compare the kinetic energy of the truck as it left the quarry with its kinetic energy on the way to the quarry. Explain your answer.
