The puck in the figure below has a mass of 0.246 kg. Its original distance from the center of rotation is 40.0 cm, and it moves with a speed of 65.0 cm/s. The string is pulled downward 15.0 cm through the hole in the frictionless table. Determine the work done on the puck. Hint: Consider the change in kinetic energy of the puck.
