How Does Pulling the String Affect the Speed of a Ball in Circular Motion?

[QUOTE="Koko$, post: 5334498, member: 581809"] The ball is set into motion on circular path of radius R. Ball is connected to a string, at the bottom of the string, the force acting downward is applied, so the radius(R) is decreased. I found similar problem in web, but there is no force applied, but the mass M. So maybe I should just convert force into mass, aply to the ##F_C## formula and from this ##F_C## calculate the final velocity,.. but how much shorter will be the string(radius) if the force(some force - not given in numbers) is applied?
