The weight of a skier standing on the snow is 78N. Each ski is 1.95m long and 6cm wide.

The weight of a skier standing on the snow is 78N. Each ski is 1.95m long and 6cm wide. Find the pressure the skier puts on the snow.

To calculate the amount of pressure exerted by the specified skier on the snow, we apply the formula: P = Pl / S = Pl / (n * S1) = Pl / (n * l * b).

Values of variables: Pl – weight of the specified skier (Рл = 78 N); n is the number of skis (n = 2 pcs.); l – ski length (l = 1.95 m); b – width (b = 6 cm = 0.06 m).

Let’s make a calculation: P = Pl / (n * l * b) = 78 / (2 * 1.96 * 0.06) = 331.63 Pa.

Answer: The specified skier exerts a pressure of 331.63 Pa on the snow (weight 78 N (m ≈ 7.8 kg) for a skier is very small; at P = 780 N, the pressure will be 3.3 kPa).
