Two grocery carts have the same initial total momentum. The two carts collide, and now cart B has a greater final velocity.
Which best describes the final total momentum of both the carts compared to the initial total momentum?
It is less if cart B has a smaller mass.
It is greater if cart B has a greater mass.
It is the same if no external forces are added.
It depends on the masses of cart A and cart B.

It is the same if no external forces are added.
Explanation: Momentum of the isolated two-cart system is conserved during their collision because the internal forces between the carts are equal and opposite. Individual speeds can change, but the total momentum remains equal to the initial total momentum unless an external force acts (e.g., strong friction with the floor).
