under ted
One foot of the person is
280 cm2,
find the pressure exerted on the
ground by person.
​

Answer 1

Answer:

Explanation:

Given :

• Wight of a person (F) = 60 N
• Area of one foot of the person (A) = 280 cm²

To Find :

• The pressure exerted on the ground by person.

Formula to be used :

• P = F/A

Solution :

★Converting units,

A = 280 cm²

⇒ A = 280/100

⇒ A = 2.8 m²

★Pressure,

P = F/A

⇒ P = 60/2.8

⇒ P = 21.4 N/m²

Hence, The pressure exerted on the ground by the person is 21.4 N/m².

Converting Units,

A = 280 cm²

→ A = 280/100

→ A = 2.8 m²

Pressure,

P = F/A

→ P = 60/2.8

→ P = 21.4 N/m²

Hence, the pressure exerted on the ground by that person is 21.4 N/m².
