For a movie stunt, an empty truck with a mass of 2000 kg goes 10 m/s and runs into a stopped car of mass 500 kg. The truck then keeps moving and pushes the car along with it. If there are no other forces acting on this system, which best describes the results of the collision?

Group of answer choices

The momentum after the collision is greater than the momentum before the collision.

The velocity of the combined vehicles is less than the initial velocity of the truck.

The collision is perfectly elastic.

Momentum of the truck stays the same.
