A uniform can with mass M and height H is filled to the top with water. The initial mass of the water is 2M, twice the mass of the can.
(a) What is the vertical position of the center of mass of the can plus water?
(b) A small puncture is made in the can, so that the water can drain out. If the height of the water at any time is y, what is the height of the center of mass of the can plus water system, in terms of H and y?
(c) What is the minimum height of the center of mass as the water drains out?
