Question

Problem 2: Elastic collisions are extremely simple in the center-of-mass (CM) frame. CM frame is where the center of mass remains at rest ($dR_{cm}/dt = 0$). Show, in the CM frame, that two particles always leave the collision in exactly opposite directions and with the same individual speeds as before the collision.
