In a collision, the total momentum of a system is conserved, provided no external forces act on it. Since the initial momentum of the billiard ball is 3 kg⋅m/s, and assuming this is a closed system with no external forces, the total momentum after the collision must also equal 3 kg⋅m/s.
Therefore, the correct response is:
3 kg⋅m/s
