Understanding Momentum in Collisions: Truck vs. Car Velocity Change

[StephenDoty]

If a truck and a car collide will they both have the same change in velocity?

Since the momentum before has to equal the momentum afterward wouldn't the change in the velocity also be equal?

Thank you.

No, because they have different masses. Their change in momentum will be equal, p=mv.
