Answer 1

When the ball on the left is pulled to the side and released, it will swing back toward its original position and hit the ball on the right. Since both balls have the same mass, when the first ball collides with the second, it will transfer its momentum to the second ball. As a result, the ball on the left will come to a stop, and the ball on the right will swing to the right.

Therefore, the correct response is:

The ball on the right will swing to the right.
