A puck of mass m on a horizontal, frictionless table is connected to a string that passes through a small hole in the table. The puck is set into circular motion of radius R, at which time its speed is vi. If the string is pulled from the bottom so that the radius of the circular path is decreased to r, what is the expression for the final speed vf of the puck?

A small 0.270-kg object moves on a frictionless horizontal table in a circular path of radius 1.70 m. The angular speed is 9.60 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of the circle. Someone under the table begins to pull the string downward to make the circle smaller. If the string will tolerate a tension of no more than 102 N, what is the...
