You do an experiment with colliding cars on a low-friction track. Car 1 of mass 0.5 kg is moving in the direction at a speed of 2 m/s when it collides with Car 2 of mass 1.0 kg which is at rest. After the collision, Car 1 rebounds and moves to the right with a speed of 0.67 m/s. Define the system as Car 1.
- What is the change in the momentum of the system as a result of the collision?
- What objects in the surroundings interact with the system during the collision and what is the change in the momentum of the surroundings?
- What is the velocity of Car 2 after the collision?
