The total momentum of two marbles before a collision is. 06 kg·m/s. No outside forces act on the marbles. What is the total momentum of the marbles after the collision?

0.06kgm/s

Explanation:

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

If the total momentum of two marbles before collision is 0.06kgm/s and no outside marbles acts on them, then the momentum of the bodies after collision will also be 0.06kgm/s. This type of collision is elastic i. e both momentum and energy are conserved since no external force acts on them.
