Question

Two particles collide, one of which was initially moving and the other initially at rest. Is it possible for both particles to be at rest after the collision?

Answer 1

Answer:

Not possible

Explanation:

Unless there's some extra external force to keep both particles at rest after the collision, the momentum must be conserved before and after the collision.

So before the collision, 1 particle is at rest, 1 not ->  total momentum is non-zero

After the collision, both particles are at rest -> total momentum is zero which is different from before.

Therefore this is not possible.

Answer 2

It is not possible for the two objects to remain stationary after collision.

Law of conservation of momentum

According to the law of conservation  of momentum, momentum before collision is equal to the momentum after collision.

Hence, if the two particles remain stationary after collision, the law of conservation of linear momentum have not been obeyed therefore it is not possible for the two objects to remain stationary after collision.
