Draw two diagrams for the situation where a moving train (with initial speed V0) collides elastically with a target train that is not initially moving, and the trains use their springy bumpers to bounce off each other without damage. One diagram should show the instant just before the collisions and the other the instant just after the collision. Assume the trains have different masses (m-moving, and m-target). /make sure you identify your isolated system. Show the final velocity of each train using V0, m-target, and m-moving.
