Question

What pressure does a 130-pound women exert on the floor when she

balances on one of her heels? Her heels have a radius of 0.25 inches. *

Answer 1

Pressure,
`P=4.56* 10^6\ Pa`

Explanation:

Given that,

Force exerted by woman on the floor, F = 130 pounds = 578.26 N

Radius of her heels, r = 0.25 inches = 0.00635 m

We need to find the pressure exerted by woman on the floor. We know that pressure exerted by an object is equal to the force acting per unit area. So,

`P=(F)/(A)\\\\P=(578.26 \ N)/(\pi (0.00635\ m)^2)\\\\P=4.56* 10^6\ Pa`

So, the pressure exerted by the woman on the floor is
`4.56* 10^6\ Pa`.
