Question

A bomb in outer space is moving at a constant speed in a straight line. It explodes into pieces of different sizes and shapes. After the explosion:
(A) the momentum of each piece is identical.
(B) the total momentum is increased since energy was released by the explosion.
(C) the momenta of all the pieces add up to zero.
(D) the momenta of all the pieces add up to be equal to the momentum of the bomb before it
exploded.
(E) More information is needed to determine if any of the above answers are correct.

Explanation / Answer

a)false,total momentum will be conserved but ot the momentum for the parts
b)false,momntum is conserved
c)false,initially the bomb has the momentum and it remains constant after the explosion
d)true,momentum is conserved in all the collisons or explosions

D is the answer
