# Which statement best describes the situation? Which statement best describes the situation? The car has the greater change of momentum because it has the greater speed. The truck has the greater change of momentum because it has the greater mass. Neither the car nor the truck changes its momentum in the collision because momentum is conserved. They both have the same change in magnitude of momentum because momentum is conserved. None of the above is necessarily true.

Complete Question

A truck going 15 km/h has a head-on collision with a small car going 30 km/h. Which statement best describes the situation?

A. the truck has the greater change of momentum because it has the greater mass

B. the car has the greater change of momentum because it has the greater speed

C. neither the car nor the truck changes its momentum in the collision because momentum is conserved

D. they both have the same change in magnitude of momentum because momentum is conserved

E. none of the above is necessarily true

D. They both have the same change in magnitude of momentum because momentum is conserved

Explanation:

In order to get a good understanding of the solution above we define some

concetps

Momentum

This is defines quantified motion and can be mathematically represented as

Momentum = Mass of the body * Velocity of the body

According to the Law of conservation of momentum states that when two particles collide together in a system that is being isolated that their total momentum before and after their collision is equal this means that the momentum lost by the truck would be the same as the momentum gained by the small car
