What pressure does a 70 kg snowboarder produce on the snow, if the support area of the ski is 0.35 m?

Given:

m = 70 kilograms – the weight of the snowboarder;

s = 0.35 meters squared – the reference area of ​​the snowboard.

It is required to determine P (Pascal) – the pressure that the snowboarder produces on the snow.

Since the problem statement is not specified, the weight of the snowboard itself is not taken into account.

The gravity acting on the snowboarder will be equal to:

F = m * g (where g = 10 N / kg is an approximate value);

F = 70 * 10 = 700 Newtons.

Then, to determine the pressure, you must use the following formula:

F = P * s, from here we find that:

P = F / s = 700 / 0.35 = 2000 Pascal (2 kPa).

Answer: The snowboarder produces a pressure of 2000 Pascal (2 kPa) on the snow.
