A girl is whirling a ball on a string around her head in a horizontal plane. She wants to let go at precisely the right time so that the ball will hit a target on the other side of the yard. When should she let go of the string?

If the girl releases the string the ball will fly away in the tangentional direction. Why? Because when she releases the string, there will be no more centripetal force draging the ball toward the center. Because of the inertion, the ball will fly away in the direction of the speed adn acceleration acting on its motion. In this case, it will be the direction of tangent to the circular path in the moment of release.
