Question

A girl has a weight of 450 N and her feet have a total area of 300Cm2

Answer 1

Answer:

15000N/m²

Explanation:

Given parameters:

Force exerted by the girl  = 450N

Area  = 300cm²

Unknown:

Pressure exerted by her feet  =?

Solution:

Pressure is the force per unit area on a body;

    Pressure  = $\frac{force }{area}$

We need to convert the given area to m²;

        10000cm²   =  1m²

        300cm²  = $\frac{300}{10000}$   = 0.03m²

Pressure = $\frac{450}{0.03}$   = 15000N/m²
