Question: An 8 . 5 - kgkg shell at rest explodes into two fragments, one with a mass of 2 . 0 kg and the other

An 8.5-kgkg shell at rest explodes into two fragments, one with a mass of 2.0 kg and the other with a mass of 6.5 kg. If the heavier fragment gains 130 JJ of kinetic energy from the explosion, how much kinetic energy does the lighter one gain?
