# A truck going \(15 \, \text{km/h}\) has a head-on collision with a small car going \(30 \, \text{km/h}\). Which statement best describes the situation?

A truck going \(15 \, \text{km/h}\) has a head-on collision with a small car going \(30 \, \text{km/h}\). Which statement best describes the situation?

- **A.** The truck has the greater change of momentum because it has the greater mass.
- **B.** They both have the same change in magnitude of momentum because momentum is conserved.
- **C.** The car has the greater change of momentum because it has the greater speed.
- **D.** Neither the car nor the truck changes its momentum in the collision because momentum is conserved.
- **E.** None of the above is necessarily true.
