A skier is standing still on a flat area of snow.
The weight of the skier is 550 N. The total area of his skis in contact with the ground is 0.015
m2.
What is the pressure exerted on the ground by the skier?

3700 N / m2
37 000 N/m2
8.3 N/m2
0.83 N/m2

Sagot :

  • Force=550N
  • Area=0.015m^2

We know

[tex]\boxed{\sf Pressure=\dfrac{Force}{Area}}[/tex]

[tex]\\ \sf\longmapsto Pressure=\dfrac{550}{0.015}[/tex]

[tex]\\ \sf\longmapsto Pressure=36666Pa[/tex]

[tex]\\ \sf\longmapsto Pressure=36666N/m^2[/tex]

Most nearest value is 37000N/m^2

Hence option b is correct
