A puck on a frictionless air-hockey table has a mass of 0.0500kg and is attached to a cord passing downward through a hole in the table. The puck is originally revolving at a distance of 0.300m from the hole with an angular speed of 2.50 rad/s. the cord is then pulled from below l, shortening the puck' s radius to 0.100m. what is the buck's new angular speed?
