Answer 1

When the ball on the left is pulled to the side and released, it will swing back and collide with the ball on the right. Since both balls have the same mass and are touching each other, the result of the collision will be that the ball on the left will stop, and the ball on the right will swing to the right.

So, the correct response is:

The ball on the left will stop, and the ball on the right will swing to the right.
