Question

What is the ratio of the force exerted on the floor by the ground to the persons body weight

Answer 1

We will have the following:

We are given:

m = 67kg

F = 2300N

Now, we have that the average are of a human foot is approximately 76 cm^2.

So, we will deterine the ratio of force excerted on the floor in terms of pressure, that is:

$P=\frac{2300N}{0.0076m^2}\Rightarrow P=302631.5789Pa$$\Rightarrow P\approx302.632kPa$

So, the ratio of the force exerted on the floor by the ground is approximately 302.632 Kilopascals.
