The sole of a tennis shoe has a surface area of 0.0290 m^2. if it is worn by a 65.0 kg person, what pressure does the shoe exert on the ground?

21965.517 Pa

Explanation:

Pressure is the force exerted by a gas, a liquid or a solid on a surface (or area) , its unit is Pascal which is equal to and its formula is:  

(1)

In this case we have the surface of a sole of a tennis shoe:

(2)

And the mass of the person who wears it:

On the other hand, we know the weight is the force   the Earth exerts on people and objects due gravity :

(3)

Substituting (2) and (3) in (1):

(4)

Finally:

This is the pressure the shoe exert on the ground

.
