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?

Responses
1) less the 3 kg * m/s
2) It depends on the mass of each ball
3) more then kg * m/s
4) 3kg * m/s

2) It depends on the mass of each ball

out of these repsonses what is the closest answer

4) 3 kg * m/s
