A 900-N person is standing on snowshoes.Each snowshoe has area 2500 cm² and has negligible weight.What pressure does this person's exert on the snow due to his interaction with Earth?

Question

Quizplus · Accepted Answer

Pressure is calculated as force divided by area. The total area of both snowshoes is $2 \times 2500 \, \text{cm}^2 = 5000 \, \text{cm}^2 = 0.5 \, \text{m}^2$ (since $1 \, \text{m}^2 = 10000 \, \text{cm}^2$). The force exerted by the person is 900 N. Therefore, the pressure is $900 \, \text{N} / 0.5 \, \text{m}^2 = 1800 \, \text{N/m}^2$.
