Question

A girl has a weight of 450 N and her feet have a total area of 0.0300 m2. Calculate the pressure her feet put on the ground.

Answer 1

15000N/m²

Step-by-step explanation:

Given parameters:

Weight = 450N

Total area = 0.03m²

Unknown:

Pressure under her feet = ?

Solution:

Pressure is the force per unit area on a body.

Pressure =
`(Force )/(Area)`

Weight is a type of force;

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