While playing pool, the white cue ball strikes the 8 ball. Before the collision, the cue ball's velocity was +10 m/s and the 8 ball was at rest. If both ball's have a mass of 0.15 kg and the cue ball's velocity after the collision is +2 m/s, what is the 8 ball's velocity?

• +2 m/s

• +8 m/s

• -2 m/s

• +1.5 m/s
