Question

Two cars collide. The total momentum in the system before the collision is 2,000 kg*m/s. What is the total momentum in the system after the collision?​

Answer 1

total momentum of the two cars after they collide= 100 kg m/s

Step-by-step explanation:

We use law of conservation of momentum which says that , for an isolated system , total momentum before collision is equal to the total momentum after the collision.

Total momentum of two cars before collision= 100 kg m/s

so the total momentum of the two cars after the collision= 100 kg m/s

Step-by-step explanation:

Answer 2

The total momentum in the system after the collision is also 2,000 kgm/s. This is because the total momentum of a closed system (such as two colliding cars) is conserved, meaning that the total momentum before the collision is equal to the total momentum after the collision. This is a fundamental principle of physics known as the law of conservation of momentum.
