Question

anonymous · Answer

What is the definition of pressure?

anonymous · Answer

Alrighty. It is defined as$$P = {F \over A}$$

What force are we considering? What is the area that is distributed over?

anonymous · Answer

the force of the man on the snow, over a surface area of 0.02m^2. And pressure is defined as the normal force to an area per unit area.

anonymous · Answer

Exactly. so$$P = {mg \over A}$$

anonymous · Answer

so: (80(9.81))/0.02?

anonymous · Answer

That's it!

anonymous · Answer

Thank you so much!! :)

area should be doubled due to two shoes..
