Two 125 kg bumper cars are moving toward each other in opposite directions. Car X is moving at 10 m/s and Car Z at –12 m/s when they collide head–on. If the resulting velocity of Car Z after the collision is 10 m/s, what is the velocity of Car X after the collision?

It would be nice to know the direction of Car Z. And it would be nice to know if it were an elastic collision, in reality, it is not.
