Assignment:
Two blocks are cemented together top to bottom and the whole object is placed in water. Known values are the density of the wood Dw= .650 kg/m^3, of aluminum Da = 2700 kg/m^3, and of water Dliq= 1000 kg/m^3.
PART a. If the object barely floats, with the top surface ot the wood level with the surface of the water, find the ratio of the volumes, Vw/Va.
PART b. With the object barely floating, if the mass of the aluminum part is Ma= 8 kg, find the mass of the wood part.
PART c. If the object floats with the wood only 75 percent submerged, find the ratio of the volumes, Vw/Va.
