In an elastic collision, bumper cars 1 and 2 are moving in the same direction when bumper car 1 rear-ends bumper car 2. The initial speed of bumper car 1 is 6.26 m/s and that of bumper car 2 is 4.73 m/s. The mass of bumper car 2 is 53 % greater than that of bumper car 1. Take the positive direction to be the direction in which the bumper cars are moving.   Part (a) What is the final velocity, in meters per second, of bumper car 1? Part (b) What is the final velocity, in meters per second, of bumper car 2?
