Here,
Mass of the person (m) = 60Kg
Acceleration due to gravity (g) = 10 m/s2
Area covered by one foot = 150 cm 2 = 0.015 m 2
Now pressure (p) = \(\frac{Fore(F)}{Area(A)}\)
\(=\frac{m\times g}A\)
\(=\frac{60\times10}{0.015}\)
\(=40,000\frac N{m^2}\)
Hence the pressure exerted by his one foot is 40,000 pascal. Pressure exerted by his two feet would be 20,000 Pascal.
