A 2.3 kg cart is rolling across a fricitonless, horizontal track toward a 1.5 kg cart that is held initially at rest. The carts are loaded wiwth strong magnets that cause them to attract one another. Thus the speed of each cart increases. At a certain instant before the carts collide, the first carts velocity is 4.5 m/s and the second carts velocity is -1.9 m/s. What is the total momentum of the systems of the two carts at this instant? what was teh velocity of the first cart when the second cart was still at rest?
