Question

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

Answer 1

15000N/m²

Step-by-step 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 =
`(force )/(area)`

We need to convert the given area to m²;

10000cm² = 1m²

300cm² =
`(300)/(10000)` = 0.03m²

Pressure =
`(450)/(0.03)` = 15000N/m²
