The total momentum of a styem of two moving identical bodies is zero . what should be true about velocities of the bodies?
1 answer
If the total momentum of a system of two moving identical bodies is zero, it means that the momentum of one body is equal in magnitude and opposite in direction to the momentum of the other body. Therefore, the velocities of the bodies must also be equal in magnitude and opposite in direction in order to have a total momentum of zero. This means that the bodies are moving towards each other, with one body moving in one direction and the other body moving in the opposite direction, such that their momenta cancel out.
