Car 1 and Car 2 have equal masses of 2,000 kg each. Car 1's initial momentum was 40,000 kg-m/s to the right; Car 2 wasn't moving.
Car 1 collided with Car 2.
Car 1's final velocity is 10 m/s to the right; Car 2's final velocity is unknown.
1. What is each car's initial velocity?
2. What is their total initial momentum?
3. After the collision, what is Car 2's final velocity?
4. What is their total final momentum?

Please dont answer unless you can help
