1. Two children are in separate bumper cars and drive into each other in an elastic collision. The first child and his car had a combined mass of 252 kg and was traveling 2.1 m/s [N 20E] when he hit the other bumper car with a combined mass of 260 kg that was traveling 2.6 m/s [S]. After the collision the first child's bumper car (m=252 kg) travels east and the second bumper car (m=260 kg) travels [N 8E]. Determine the velocities of both bumper cars just after the collision.
