Determine the new angular velocity

Reference no: EM13315483

A block is attached to a chord passing over a pulley through a hole in a horizontal frictionless surface. Initially, the block is revolving with an initial angular speed of 4 rad/sec at a distance r from the center of the hole. If the chord is pullef from below until its radius is r/4, what is the new angular velocity?
