A projectile in flight explodes into several fragments.The total momentum of the fragments immediately after this explosion:
A)is the same as the momentum of the projectile immediately before the explosion
B)has been changed into kinetic energy of the fragments
C)is less than the momentum of the projectile immediately before the explosion
D)is more than the momentum of the projectile immediately before the explosion
E)has been changed into radiant energy

Question

Quizplus · Accepted Answer

The law of conservation of momentum states that the total momentum of a system remains constant if no external forces act on it. Therefore, the total momentum of the fragments immediately after the explosion is the same as the momentum of the projectile immediately before the explosion.
