SUMMARY
The firework explosion problem involves a firecracker that explodes into three equal mass pieces at its peak height. Two pieces move at 130 m/s at right angles to each other, while the third piece's velocity must be determined using the conservation of momentum principle. The initial momentum is zero, and the final momentum must also equal zero, leading to the conclusion that the third piece moves at 130 m/s in a direction that balances the momentum of the other two pieces.
