Question

As a stands, her entire weight is momentarily placed on the heels of her high-heeled shoes. Calculate the pressure exerted on the floor by the heels if the heels are circular with a radius of 0.578 cm, and the woman’s mass is 65.0 kg. Express the pressure in Pa.

Answer 1

Pressure will be
`6072449.952Pa`

Step-by-step explanation:

We have given mass of the women m = 65 kg

Radius of the heels r = 0.578 cm = 0.00578 m

We have to find the pressure

We know that pressure is given by

`P=(F)/(A)=(mg)/(A)`

So force F = mg = 65×9.8 = 637 N

Area
`A=\pi r^2=3.14* 0.00578^2=1.049* 10^(-4)m^2`

So pressure
`p=(637)/(1.049* 10^(-4))=6072449.952Pa`
