In an elastic collision, a 355 kg bumper car collides directly from behind with a second bumper car that is traveling in the same direction. The mass of the leading bumper car is 30.0% greater than that of the trailing bumper car. The initial speed of the leading bumper car is 3.70 m/s, and that of the trailing car is 7.70 m/s. Assuming that the mass of the drivers is much, much less than that of the bumper cars, what are their final speeds? (Enter your answers in m/s. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) leading bumper car m/s trailing bumper car m/s
