3. On a vacation trip up in Oregon my boys decided to build a 10 kg raft that they made out of driftwood. They decided to try out their raft on a pond nearby and it floats. The density of the pond water is 1000 kg/m³ and the density of the drift wood is 685 kg/m³. b. a. Calculate the volume of the raft. c. b. Calculate the magnitude of the buoyant force on the raft and state its direction Next they decide to add weights to the raft to test how much it can hold. They find some metal weights in the garage that are made out of brass (density = 8,000 kg/m3) and they add them one at a time until the raft is fully submerged. a. C. Determine the new buoyant force on the raft. b. d. What was the amount of mass added to the raft that would cause it to be fully submerged but not sink?

Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). (a) What mass of water is displaced? (b) What is the volume of the bone? (c) What is its average density?
