Question

A billiard ball moves with 3 kg⋅m/s of momentum and strikes three other billiard balls. What is the total momentum of the balls after the collision?(1 point)
Responses

less than 3 kg⋅m/s
less than 3 kilograms times meters per second

more than 3 kg⋅m/s
more than 3 kilograms times meters per second

It depends on the mass of each ball.

3 kg⋅m/s

Answer 1

The total momentum of a system before and after a collision is conserved, assuming no external forces act on the system. Therefore, the total momentum after the collision will be the same as the total momentum before the collision.

Given that the initial momentum of the billiard ball is 3 kg⋅m/s, the total momentum of the balls after the collision will also be 3 kg⋅m/s.

So, the correct response is:

**3 kg⋅m/s**
