A lady wearing high heels shoes has a weight of 550 N. area of the sole of each of the lady's shoes is 1.25 cm ^2 calculate the pressure exerted by the lady.

Answer & Explanation:

area of one sole = 1.25 cm^2

therefore area of 2 soles = 1.25 x 2 = 2.5cm^2

USE THE FORMULA

P = F / A

convert cm^2 to m^2

2.5/10000 = 2.5 x 10^-4 m^2

P = 550 / 2.5 x 10^-4

P = 2.2 x 10^6 Pa
