A person is floating in fresh water with 88% of their body submerged. What is the density (in kg/m3) of the person?
When a body is submerged in water, its weight is balanced by the upthrust. Therefore
If V is the volume of the person, is his density, Vin is the volume of the person inside water and is the density of water, then
Given 88% of the volume of the person is submerged. Therefore,
Also the density of water, = 1000kg/m^3. So,
So the density ofthe person is 880 kg/m^3.
