A puck of mass 0.1 kg slides in a circular path on a horizontal frictionless table at an angular velocity ? of 20 rad/s. It is held at a constant radius of 1 meter by a string threaded through a frictionless hole at the center of the table. Then, you pull on the string such that the radius decreases by a factor of 2. What happens to the angular velocity of rotation?
