A person weighing 200 pounds stands on snowshoes. If the area of each snowshoe is 400 square inches, the pressure on the snow is

0.5 pounds per square inches (ibs/in²)

Explanation:

The pressure of an object refers to the force it exerts per unit area i.e. F/a. In this question, the force, F, is created by the weight, W, of the snowshoe. Hence, pressure is calculated thus:

P = W/A

Where; P = Pressure (ibs/in²)

W = Weight of object (ibs)

A = surface area (in²)

In this question, weight = 200 pounds, Area = 400 square inches

Hence, pressure = 200/400

Pressure (P) = 2/4

Pressure (P) = 0.5 ibs/in²
