What pressure on the floor is produced by a person whose mass is 32 kg, and the area

What pressure on the floor is produced by a person whose mass is 32 kg, and the area of the soles of his shoes is 0.032 m2?

Given:

m = 32 kilograms – the mass of a person;

s = 0.032 meters squared – the area of the soles of a person’s shoes (support area).

It is required to determine P (Pascal) – the pressure that a person produces on the floor.

Let’s find the force of gravity acting on a person:

F = m * g (where g = 10 N / kg is an approximate value);

F = 32 * 10 = 320 Newtons.

Then, to determine the pressure, you must use the following formula:

F = P * s, from here we find that:

P = F / s;

P = 320 / 0.032 = 10000 Pascal (10 kPa).

Answer: a person produces a pressure equal to 10,000 Pascals (10 kPa) on the floor.
