Question

If a person stands is wearing shoes, their 160 lb weight is distributed over the bottoms of two shoes, with a total area of about 0.8ft. What is the pressure they exert on the ground?

Answer 1

The pressure exerted by the person wearing shoes with a total area of 0.8ft² is 890 N/ft².

Step-by-step explanation:

Pressure is defined as the force exerted on a surface per unit area. In this case, we can calculate the pressure exerted by the person on the ground by dividing their weight by the total area of the shoe bottoms.

First, convert the weight of the person from pounds to newtons: 160 lb * 4.45 N/lb = 712 N. Then, divide the weight by the total area of the shoe bottoms: 712 N / 0.8 ft² = 890 N/ft².

Therefore, the person exerts a pressure of 890 N/ft² on the ground when wearing shoes with a total area of about 0.8ft².
