A 1.0-kg cue ball traveling at 15 m/s strikes a stationary billiard ball of mass 1.5 kg. After the collision, the cue ball remains at rest. With what velocity does the other ball travel?

Other ball's velocity is 10 m/s

Explanation:

We can use conservation of momentum:

wavelegth as in spectrum red oygbiv

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
