A 540-newton woman can make dents in a hardwood floor wearing high-heeled shoes, yet if she wears
snowshoes, she can step effortlessly over soft snow without sinking in?

Explanation:

To explain this problem, we need to broach over the concept of pressure.

Pressure is the force applied per unit area on a body.

         Pressure  =

We see that the higher the force, the higher the pressure applied. Pressure is directly proportional to force.

Area shares an inverse relationship with pressure. The higher the pressure the lower the area and vice versa.

A high-heeled show shoe has a very small surface area compared to the surface of snowshoes which are larger.

For the same weight which is the downward force of the woman, the high-heeled shoe will have a higher pressure compared to the snow shoe.

The woman works effortlessly over soft snow without sinking in because the snow shoe generates a lower pressure compared to the heeled shoe
