In a certain experiment, you fill a bucket half way up with water and then set the bucket in the freezer until the water freezes into a block of solid ice. You then remove the bucket from the freezer and set it into rotational motion on a rotating platform. Neglect any friction in the axle bearings of the platform. As the ice in the bucket melts, what will happen to the angular speed of the bucket? Explain.
