A lab is conducted with two carts of unknown masses. The carts initially start at rest and move apart so both carts travel in opposite directions. Cart A’s velocity is found to be 12 m/s to the left, while Cart B’s velocity is found to be 9 m/s to the right. What conclusions can be drawn from the experiment?
