Question

A man weighing 1500N exerts a pressure of 100N/m square on the ground. Calculate his area of contact with the ground​

Answer 1

Answer:

$\boxed{\mathfrak{Area \ of \ contact \ (A) = 15 \ m^2}}$

Given:

Force (F) = 1500 N

Pressure (P) = 100 N/m²

To Find:

Area of contact (A) with the ground

Explanation:

Formula:

$\boxed{ \bold{Pressure \: (P) = \frac{Force \: (F)}{Area \: (A)} }}$

$\implies \bold{A = \frac{F}{P}}$

Substituting value of F & P in the equation:

$\sf \implies A = \frac{15 \cancel{00}}{ \cancel{100}} \\ \\ \sf \implies A = 15 \: {m}^{2}$

$\therefore$

Area of contact (A) with the ground = 15 m²
