As a bullet travels through the air, it slows down due to air resistance. How does the bullet’s momentum change as a result?

There are two cars, car A and car B. Mass of car A is 10000 kg, travelling at 30 collide with car B of mass 30000 kg travelling at 20 in same direction. After collision, the velocity of car A becomes 40 . Calculate the velocity of car B after the collision?

There are two cars, car A and car B. Mass of car A is 2000 kg, travelling at 30 collide with car B of mass 3000 kg travelling at 40 in same direction. After collision, the velocity of car A becomes 50 . Calculate the velocity of car B after the collision?

Law of conservation of momentum states that

1. The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them    
2. Magnitude of the final momenta = magnitude of the initial moment.    
3.    
4. All the above
