Question

For a car of weight 9000 N , the recommended tyre pressure is 18 Pa. find the area of each tyre in contact with the ground

Answer 1

Answer:

125 m^2

Explanation:

According to the given question,

F = Force = 9000 N

P = pressure = 18 Pa

A = Total Area

And we are asked to find the area of each tyre in contact with the ground.

We know,

P = F/A

A = F/P

Putting the values we get,

A = 9000/18

A = 500 m^2

As there are 4 tyres in a car, thus area of each tyre will be,

A' = 500/4 = 125 m^2

Where A' = the area of each tyre in contact with the ground.
