Example: Elastic Collision in 1DTwo masses approach each other with equal and opposite velocities as measured in the lab reference frame. The mass moving to the right is twice as massive as the one moving to the left. The collision between them is elasticWhat is the velocity of the center of mass before the collision? What is the velocity of the center of mass after the collision? What are the velocities of the two objects after the collision? . Mechanics Review 3, Slide 3 )
