What pressure does a boy weighing 50 kg, standing on skis, put on the snow. the length of one ski is 1.75 m

What pressure does a boy weighing 50 kg, standing on skis, put on the snow. the length of one ski is 1.75 m, the width is 10 cm.

First, we need to determine the total area of contact between the skis, on which the boy is standing, with the snow:

10 cm is 0.1 m;

S = a * b (by default, we will take the contact area of one rectangular ski);

1.75 * 0.1 = 0.175;

2 * 0.175 = 0.35 (after all, there are two skis).

As we know from the course of school physics, pressure is calculated in such cases by the formula:

p = F / s, where F is the force, which is equal to m * g.

Then we get:

p = 50 * 10: 0.35 ≈ 1428.57.

Answer: The boy has a pressure of 1428.57 Pa.
