In elastic collisions, total kinetic energy and momentum are both conserved. On a frictionless track, cart 1 is moving with a constant, rightward(+) velocity of 1.0m/s. Cart 2 is also moving rightward with constant velocity of 5.0m/s. After a while, cart 2 collides cart 1 from behind.(It is an elactic collision.)If the final velocity of cart 2 becomes 3.0m/s, what is the final velocity of cart 1?(SHOW ALL YOUR WORK.)
