If wind blows at 35 m/s over a house, what is the net force on the roof if its area is 240 m2 and is flat?

2. Relevant equations

Pat + 1/2 * pair * v^2

3. The attempt at a solution

wind velocity - v - 35

area of roof - A - 240

density of air - p - 1.29

atmospheric pressure - Pat - 100,000

Fnet=?

P = total pressure = Pat + 1/2 * p * v^2

Fnet = P * A = 24,200,000 N

but answer provided was 1.9 * 10^5 N
