Newton's First Law of Motion:
An object at rest will stay at rest; an object in motion will stay in motion with the same speed and direction, unless acted upon by an unbalanced force. |

As the golf ball moves around the rim, it pushes upon the rim and the rim pushes back on the ball. This provides an unbalanced force upon the ball. But once the rim ends and the ball is no longer in contact with it, the mutual interaction between wall and ball is over. At that time, the forces acting upon the golf ball are balanced and the motion of the ball is best described by Newton's first law of motion (stated in the Know the Law section). The direction the ball is moving when it reaches the edge of the rim is the direction the ball will continue to move. Make O' Isaac proud and get this one right.
