Figure 1 shows two bumper cars, Car X and Car Y, before and after they collide.

The arrows show the direction of movement of each car before and after the collision. The arrows are not to scale.
Explain how momentum is conserved in this collision. Use Newton's third law and Newton's second law in your answer.
Newton's second law can be written as:
force=change in momentumtime \text{force} = \frac{\text{change in momentum}}{\text{time}} force=timechange in momentum
