In an inelastic collision involving an isolated system,the final total momentum is
A)exactly the same as the initial momentum.
B)more than the initial momentum.
C)less than the initial momentum.

Question

Quizplus · Accepted Answer

In an isolated system, there is no external force acting on the bodies, hence the momentum remains conserved. Even during an inelastic collision, where the bodies stick together and move as a single object, the total momentum before and after the collision remains the same. Hence the correct answer is A) exactly the same as the initial momentum.
