Wrapping around a pole
Â
A puck of mass m on frictionless ice is attached by a horizontal string of length  to a very thin vertical pole of radius R. The puck is given a kick and circles around the pole with initial speed v0. The string wraps around the pole, and the puck gets drawn in and eventually hits the pole. What quantity is conserved during the motion? What is the puck’s speed right before it hits the pole?
