Assignment:
A pair of bumper cars in an amusement park ride collide elastically as one approaches the other directly from the rear.
One has a mass of m1 = 464 kg and the other m2 = 560 kg, owing to differences in passenger mass. If the lighter one approaches at v1 = 4.32 m/s and the other is moving at v2 = 3.69 m/s, calculate the velocity of the lighter car after the collision.
