A person weighing 900 N is standing on snowshoes. Each snowshoe has area 2500 cm2 and has negligible weight.
What pressure does this person's weight exert on the snow?

Respuesta :

Pressure exerted by person's weight on the snow is 1800 N/m²

Explanation:

A person weighing 900 N is standing on snowshoes.

Weight of person  = 900 N

Each snowshoe has area 2500 cm² and has negligible weight.

Number of snow shoes = 2

Total Area of snow shoes = 2 x 2500 = 5000 cm² = 0.5 m²

We have pressure is the ratio of normal force to area.

[tex]\texttt{Pressure, P} = \frac{\texttt{Force, F}}{\texttt{Area, A}}\\\\\texttt{Pressure, P} = \frac{\texttt{Weight}}{\texttt{Area}}\\\\\texttt{Pressure, P} = \frac{900}{0.5}=1800N/m^2[/tex]

Pressure exerted by person's weight on the snow = 1800 N/m²
