What pressure is exerted on the snow by a skier weighing 65 kg, if the length of the ski is 2 m and the width is 10 cm.

Problem data: m (skier’s weight) = 65 kg; L (length of each ski) = 2 m; s (width of each ski) = 10 cm (0.1 m).

Reference values: g (acceleration due to gravity) = 9.8 m / s2.

The pressure that the skier’s mass will exert on the snow is determined by the formula: P = Fт / S = m * g / 2S = m * g / (2 * L * s).

Let’s make the calculation: P = 65 * 9.8 / (2 * 2 * 0.1) = 1592.5 Pa.

Answer: The skier exerts a pressure of 1592.5 Pa on the snow.
