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 piece B moving in the positive x direction. The masses of both pieces are indicated in, shown traveling in opposite directions. What is the magnitude of the momentum |p_A, i| of piece A before the explosion? Express your answer numerically in kilogram meters per second. During the explosion, is the magnitude of the force of piece A on piece B greater than, less than, or equal to the magnitude of the force of piece B on piece A? The component of the momentum of piece B. p_Bx, f, is measured to be +500 kg middot m/s after the explosion. Find the component of the momentum p_Ax, f of piece A after the explosion. Enter your answer numerically in kilogram motors 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
