The pressure is $3.94\cdot 10^7 Pa$

Explanation:

First of all, we calculate the area of the tip of the nail, which is given by:

$A=\pi r^2$

where

r = 0.0025 m is the radius

Substituting,

$A=\pi (0.0025)^2=1.96\cdot 10^{-5} m^2$

Then we can calculate the pressure exerted by the person on the nail, which is

$p=\frac{F}{A}$

where

F = 773 N is the force exerted (the weight of the man)

$A=1.96\cdot 10^{-5} m^2$ is the area

Substituting,

$p=\frac{773}{1.96\cdot 10^{-5} m^2}=3.94\cdot 10^7 Pa$
