Question

A person weighs 60kg.The area under one foot of the person is 180 cm 2

.Find the

pressure (in SI unit) exerted on the ground by the person.​

Answer 1

Answer:

33000 n/m²

Explanation:

As p=F/A

F=mg

F=60.10=600

A=180/10⁴

upon solving we get

P=33000 N/M²

Answer 2

Answer:

33.3Pa

Explanation:

1. Convert the Kg into The mass, so that is 60kg x 10 that will be 600.
2. Then convert 180 cm² into m². So the answer will come like this: 1m²=10^-4 cm² So 180 x 10^-4 that will be 18x10^-3.
3. Now by taking the formula, Pa = N/ m²...do the calculation
4. 600/(18 x 10^-3)

• = 600x 10³/18
• So by cutting 600 by 18, we get 100/3
• Now divide 3 to 1000.
• The answer will be 333.33
• Now we multiply it by 100.
• It's will be 33.3pa

So that is your final answer
