Gauged in the observers reference frame

Reference no: EM13672839

An object, with mass 12 kg and speed 30 m/s relative to an observer, explodes into two pieces, one 3 times as massive as the other; the explosion takes place in deep space. The less massive piece stops relative to the observer. How much kinetic energy is added to the system through the explosion, as gauged in the observer's reference frame?
