A cylindrical glass cup has mass m and height h. When the cup is full, it can hold a mass of water equal to 6m. When empty, the cup's center of mass is a height h/4 from the bottom. Find the height of water in the cup such that the cup is in the most stable state. (Stability is related to the position of the system's center of mass. You may ignore the thickness of the bottom of the cup.)
An aluminum cup contains 225 g of water and a 40-g copper stirrer, all at 27 °C. A 500-g sample of silver at an initial temperature of 87 °C is placed in the water. Calculate the mass of the aluminum cup
A circular disk with the rectangular hole has a radius of 0.540 m and mass of 0.440 kg. It is suspended by a point on its perimeter. The moment of inertia about this point is I_p = 1.7×10-1 kgm2.
