At the peak of its trajectory, a 995-g fireworks rocket is moving horizontally at 18.6 m/s. It’s a dud, and instead of exploding gloriously, it bursts into two pieces. One of them, with mass 282 g, continues in the original direction at 31.3 m/s. How much energy did the two pieces gain when the rocket burst?
