The graph shows that the velocity before the cart hits the backstop is around 0.720 m/s and the velocity after is about -0.675 m/s. What other information would you need to calculate the change in momentum?

• mass of the cart

• average force exerted on the cart

• time that the force acted on the cart

• mass of the backstop
