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?

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

The answer is c. 100 kg m/s
