A life preserver is manufactured to support a 70 kg person with 25% of his volume out of the water. If the density of the life preserver is 100 kg/m^3 and it is completely submerged, what must its volume be? Assume that the density of the person to be about the same as the density of water, 1000 kg/m^3. Express your answer with the appropriate units.
A block of wood has a mass of 3.71 kg and a density of 515 kg/m3. It is to be loaded with lead (1.13 × 104 kg/m3) so that it will float in water with 0.803 of its volume submerged. What mass of lead is needed if the lead is attached to (a) the top of the wood and (b) the bottom of the wood?
A solid, square of floating ice measuring 5 m on a side and 0.33 meter thick floats partially submerged in water. Determine the number of penguins that can stand on the ice block without any of them getting their flippers wet? (i.e. such that the top surface of the ice block floats at water level)? Assume that the mass of each penguin is 10 kg. Round your answer to the nearest whole number of penguins. Assume the density of saltwater is 1030 kg/m3 and the density of ice is 980 kg/m^3
