Consider the following two situations involving two rotating objects that are joined together somehow (a) In rewind mode, many cassette and video recorders have one spool that turns at constant angular velocity pulling the tape from the other spool. What happens to the angular velocity of the other spool as the tape moves from one spool to the other (changing the outer radii of the spools). Why? Would this work in play mode? (b) A wheel (call it wheel A)...
