ANSWER
[tex]\begin{equation*} 10,340.89\text{ }N\/m^2 \end{equation*}[/tex]EXPLANATION
First, we have to convert the weight from pounds to kilogram:
[tex]\begin{gathered} 2.2lbs=1kg \\ 130lbs=\frac{130}{2.2}kg=59.09kg \end{gathered}[/tex]Now, we can find the force exerted on the ground by applying the formula for force:
[tex]\begin{gathered} F=ma=mg \\ F=59.09*9.8 \\ F=579.09N \end{gathered}[/tex]Now, we find the pressure exerted by dividing the force exerted on the ground by the area covered by both feet in square meters:
[tex]\begin{gathered} P=\frac{F}{A} \\ \\ P=\frac{579.09}{2*280*0.0001} \\ \\ P=10,340.89\text{ }N\/m^2 \end{gathered}[/tex]That is the answer.
