The correct principle that explains the result of the collision between the carts is the **law of conservation of momentum**.
According to the law of conservation of momentum, the total momentum of a closed system before a collision is equal to the total momentum after the collision, assuming no external forces act on the system. In this case, you can calculate the initial momentum of the 10-kg cart and compare it to the total momentum after the collision to show that momentum is conserved.
