Momentum in an Explosion
Part A = 0
Part B = equal to
Part C = 500 kg·m/s
The problem tells us the egg is at rest before the explosion, so the momentum must be zero.
Remember that every action produces an equal and opposite reaction. So the two forces must be equal to each other.
Every action produces an equal and opposite reaction. Therefore, the momentums are equal. Piece A will be moving faster, since it has less mass, and piece B will be moving slower, since it has greater mass, but the momentums will be the same.
