Question

What is the downward force exerted by the atmosphere on a soccer field, whose dimensions are 105 m by 65.0 m?

Answer 1

Answer:
`6.9*10^(8)Nm^(2)`

Step-by-step explanation:

given data:

dimension of the field = 105 m by 65.0 m

atmospheric pressure: 10132.5mbar = 101325N

Solution

since a soccer field is usually a rectangle in shape, the area of the field

= l * b

`= 105 * 65\\= 6825m^2`

`P =(F)/(A)`

`F = P*A\\= 101325 * 6825\\\= 691543123Nm^(2) \\= 6.9*10^(8)Nm^(2)`
