Athlete weighing 70 kg. rides on a horizontal section on a skateboard in the shape of a rectangle 70 cm

Athlete weighing 70 kg. rides on a horizontal section on a skateboard in the shape of a rectangle 70 cm long and 20 cm wide. What is the pressure of an athlete on the snow?

To calculate the pressure of an athlete on a skateboard on the snow, we will use the formula: P = Fт / S = m * g / (L * b).
Constant and variable values: m – athlete’s weight (m = 70 kg); g – acceleration due to gravity (g ≈ 10 m / s2); L – the length of the skate (L = 70 cm = 0.7 m); b – the width of the skate (b = 20 cm = 0.2 m).
Let’s perform the calculation: P = m * g / (L * b) = 70 * 10 / (0.7 * 0.2) = 5 * 10^3 Pa = 5 kPa.
Answer: The pressure on the snow from the side of the athlete on the skateboard is 5 kPa.
