Draw two diagrams for the situation where a moving train (with initial speed v0) collides elastically with a target train that is not intially moving, and the trains use their springy bumpers to bounce off each other without damage. one diagram should show the instant just before the collision 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 that the final velocity of each train will be:
v target= 2v0/ (1+ mtarget/moving)
v moving= (m moving - m target)/ (m moving + m target) v0
