A person wears wide snowshoes to walk across soft, deep snow.
Explain why the use of snowshoes prevents the person from sinking into the snow.
The two snowshoes have a combined weight of 30 N. The weight of the person is 770 N. The total surface area of both snowshoes in contact with the snow is 0.25 m2.
Calculate the average pressure exerted on the snow when the person is standing still on both feet. Include the unit.
