A girl weighing 45 kg. stands on skis, the length of each ski is 1.5 m, the width is 10 cm.

A girl weighing 45 kg. stands on skis, the length of each ski is 1.5 m, the width is 10 cm. What pressure does the girl put on the snow?

Initial data: m (girl’s weight) = 45 kg; l (length of each ski) = 1.5 m; s (width of each ski) = 10 cm.

Reference values: g (acceleration due to gravity) = 10 m / s2.

SI system: s = 10 cm = 0.1 m.

The pressure that the girl will exert on the snow can be calculated using the formula: P = F / S = m * g / (2 * l * s).

Let’s calculate: P = 45 * 10 / (2 * 1.5 * 0.1) = 1500 Pa or 1.5 kPa.

Answer: The girl exerts a pressure of 1.5 kPa on the snow.
