Homework Help: physics

Posted by mNoellb on Saturday, February 19, 2011 at 6:16pm.

As a woman walks, her entire weight is momentarily supported on the heel of one shoe. Calculate the pressure exerted on the floor by a high-heel shoe worn by a 50-kg woman if the heel has an area of 2.0cm^2. Express the pressure in newtons per square meter and atmospheres.

I am using the formula :
P= F/A => F=mg A= 3.14(r^2)
M-50 kg
g=9.8 m/sec^2
r^2- (2cm^2)^2
I have the answer in my book so I know I'm not getting the formula right and I don't know why. Can someone please help me.
Thank you!
