What pressure does a person weighing 80 kg produce on the floor if the area is 380 cm2?
| March 22, 2021 | education
Given:
m = 80 kilograms – the mass of a person;
g = 10 m / s ^ 2 – free fall acceleration;
S = 380 cm ^ 2 = 0.038 m ^ 2 – floor surface area.
It is required to determine the pressure of a person on the floor P (Pascal).
P = F / S = m * g / S = 80 * 10 / 0.038 = 800 / 0.038 = 21053 Pascal = 21 kPa.
Answer: a person produces a pressure of 21 kPa on the floor.
