Question

The total momentum of the two cars before a collision is 100 kg m/s. what is the total momentum of the two cars after they collide?

Answer 1

The answer is c. 100 kg m/s

Answer 2

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

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
