A mass m is attached to a post of radius R by a string. Initially it is distance r from the center of the post and is moving tangentially with speed v0. Case (a) The string passes through a hole in the center of the post at the top. The string is gradually shortened by drawing it through the hole. Case (b) The string wraps around the outside of the post. What quantities are conserved in each case
