"A shell explodes into two fragments, one fragment 25 times heavier than the other. If any gas from the explosion has negligible mass, then" Selected Incorrect the kinetic energy change of the heavier fragment is 25 times as great as the kinetic energy change of the lighter fragment. Answers: the momentum change of the lighter fragment is 25 times as great as the momentum change of the heavier fragment. the momentum change of the heavier fragment is 25 times as great as the momentum change of the lighter fragment. the momentum change of the lighter fragment is exactly the same as the momentum change of the heavier fragment. the kinetic energy change of the heavier fragment is 25 times as great as the kinetic energy change of the lighter fragment. Correct the kinetic energy change of the lighter fragment is 25 times as great as the kinetic energy change of the heavier fragment
