What if...?

Sorry, unfortunately, your answer wasn't correct.

Correct is this:

The other ball (which was resting before the collision) starts to move with the velocity of the white ball while the white ball stops moving and just lies on the billard table. This means: The white ball passes its momentum onto the ohter ball. Because both balls have the same mass, their velocities are exchanged. This is an example of the law of energy conservation and the law of conservation of momentum. Collisions like this are called elastic collisions. Watch the result in the video once more!
