Question: Momentum in an Explosion
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 (Figure 1) , shown traveling in opposite directions.
A = 10kg
b = 30 kg
What is the magnitude of the momentum |pâƒ-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?
greater than
less than
equal to
The component of the momentum of piece B, pBx,f , is measured to be +500 kgâ‹...m/s after the explosion. Find the component of the momentum pAx,f of piece A after the explosion.
Enter your answer numerically in kilogram meters per second.
