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)

Question

Responses
less than 3 kg⋅m/s
It depends on the mass of each ball.

more than 3 kg⋅m/s

3 kg⋅m/s

Answer 1

The total momentum of a system before a collision must equal the total momentum after the collision, according to the law of conservation of momentum.

Since the initial billiard ball has a momentum of 3 kg⋅m/s, the total momentum of the system (the original ball plus the other three balls) after the collision will still be 3 kg⋅m/s, assuming no external forces act on the system.

Therefore, the correct response is:

3 kg⋅m/s
