Question

A giant "egg" explodes as part of a fireworks display. The egg is at rest before the explosion, and after the explosion, it breaks into two pieces, with the masses indicated in the diagram, traveling in opposite directions.

A giant "egg" explodes as part of a fireworks display. The egg is at rest before the explosion, and after the explosion, it breaks into two pieces, with the masses indicated in the diagram, traveling in opposite directions. What is the momentum pA, i of piece A before the explosion? Express your answer numerically in kilogram meters per second. During the explosion, is the force of piece A on piece B greater than, less than, or equal to the force of piece B on piece A? The momentum of piece B is measured to be 500 kg? m/s after the explosion. Find the momentum pA, f of piece A after the explosion. Enter your answer numerically in kilogram meters per second.

Explanation / Answer

1. Before the explosion, the momentum is going to be 0. This is because they are not moving yet :)

2. During the explosion, the momentums are going and opposite. Meaning the force they apply onto each other will be equal.

3. A will have an opposite force and equal momentum than B. Therefore, the momentum of A = -500 kg*m/s

Summary
1. 0
2. equal to
3. P_A=-500 kg*m/s
