17. A 2.3-kg cart is rolling across a frictionless, horizontal track toward a 1.5-kg cart that is held initially at rest. The carts are loaded with 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 cart's veloc- ity is +4.5 m/s, and the second cart's velocity is – 1.9 m/s. (a) What is the total momentum of the system of the two carts at this instant? (b) What was the velocity of the first cart when the second cart was still at rest?

17. A 2.3-kg cart is rolling across a frictionless, horizontal track toward
a 1.5-kg cart that is held initially at rest. The carts are loaded with 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 cart's veloc-
ity is +4.5 m/s, and the second cart's velocity is – 1.9 m/s. (a) What is the
total momentum of the system of the two carts at this instant? (b) What was
the velocity of the first cart when the second cart was still at rest?
