Calculate the pressure exerted on the ground due to $\text { a } 79 - \mathrm { kg }$ person standing on one foot if the bottom of the person's foot is $13 \mathrm {~cm}$ wide and $28 \mathrm {~cm}$ long.

Question

Quizplus · Accepted Answer

The pressure is calculated using the formula $ P = \frac{F}{A} $, where $ F = mg $ (force due to gravity) and $ A $ is the area. Here, $ m = 79 \, \text{kg} $, $ g = 9.8 \, \text{m/s}^2 $, and $ A = 0.13 \, \text{m} \times 0.28 \, \text{m} = 0.0364 \, \text{m}^2 $. Thus, $ P = \frac{79 \times 9.8}{0.0364} \approx 2.1 \times 10^4 \, \text{Pa} $.
