Question

Какую площадь подошвы имеет ботинок, если человек массой 80 кг стоя в нем на одной ноге оказывает давление на пол 50 кПа?​

Answer 1

Ответ:

0,016м²

Объяснение:

р=F/s

s=F/p

F=mg

F=80*10=800Н

s=800/50000=0,016м²

Answer 2

Calculating the Area of the Shoe Sole

To calculate the area of the shoe sole, we can use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

Given: - Force (F) = 80 kg * 9.8 m/s^2 (acceleration due to gravity) = 784 N - Pressure (P) = 50 kPa = 50,000 Pa

We can rearrange the formula to solve for the area (A):

Area (A) = Force (F) / Pressure (P)

Substitute the given values: Area (A) = 784 N / 50,000 Pa

Calculating the area: Area (A) ≈ 0.01568 m^2

So, the area of the shoe sole is approximately 0.01568 square meters when a person weighing 80 kg exerts a pressure of 50 kPa while standing on one foot.
