The weight of the skier with skis is 70 kg. The support area of two skis is 2300 cm2. What is the pressure exerted by the skier on the snow.

The pressure p is equal to the force F divided by the area S on which the pressure is applied: p = F / S
Given: m = 70 kg; S = 2300 cm ^ 2 = 0.23m ^ 2
Decision:
p = F / S, F = mg, we get:
p = mg / S, p = (70 • 10) /0.23 = 3043 Pa
Answer: 3043 Pa
