A small ball is attached to one end of a spring that has as an unstrained length of .200m. The spring is held by the other end, and the ball is whirled around a horizontal circle at a speed of 3.00 m/s. The spring remains nearly parallel to the ground during the motion and is observed to be stretched by .10 m. By how much would the spring stretch if it were arrached to the ceiling and the ball allowed to hang straight down, motionless?
