Suppose a man has a mass of 76kg and a density of 0.92g/cm3. A) Calculate his volume.

b) Calculate the mass of air that he displaces, using the density of air from Table 5.2. The density of air is 1.29kg/m3

c) Calculate the buoyant force on him due to the air he displaces and compare this to his weight in newtons.

A) 0.08260 cubic meter

B) 106.554 grams

C) 1.044 Newton

Step-by-step explanation:

A) Volume = mass/density

Substituting the given values, we get -

Volume = cubic centimeter

cubic meter

B) Mass = volume * density

Mass of air =

Kilogram

grams

C) Buoyant force = density * acceleration due to gravity * Volume

Buoyant force due to air  =

Kg-m/s or Newton
