Question

(b) As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. Calculate the pressure exerted on the floor by the heel if it has an area of 1.60 cm² and the woman’s mass is 55 kg. Express the pressure in 106 Pa (N/m2) for example, if the pressure is 6800000

Answer 1

P = 3.37 x 10 ⁶ Pa

Step-by-step explanation:

Given that

A= 1.6 cm²

m = 55 kg

The weight W= m g

W= 55 x 9.81 ( g= 9.81 m/s²)

W= 539.55 N

We know that force per unit area is known as pressure( P)

P = W/A

By putting the values

P= 539.55/1.6 N/cm²

P=337.21 N/cm²

P=337.21 x 10⁴ N/m²

P = 3.37 x 10 ⁶ Pa
