what is the net force on the roof if its area is 320 m^2 and is flat?
I don't even know where to start.

Carnivroar said:1/2ρv12 + p1 = 1/2ρv22 + p2
Carnivroar said:This is the answer I'm supposed to get
3.1×10^5
or 310000
Let me try it the way you said
Since V1 = 0 the first term goes away
P1 = 1/2 ρ 39^2 + P2
(1.225 = density of air)
101325 - 1/2 * 1.225 * 1521 = P2
101325 - 931.6125 = 100393.3875
100393.3875 * A = Fnet
100393.3875 * 320 = 32125884
Not right.
What am I doing wrong?
The speed of the wind blowing over the house is 39 m/s.
Yes, 39 m/s is considered a strong wind. It falls under the category of "strong gale" according to the Beaufort Wind Scale.
The higher the wind speed, the greater the force applied on the house. This force can cause damage to the structure and potentially lift or displace objects on or around the house.
No, a tornado is a specific type of weather phenomenon that requires specific atmospheric conditions and wind patterns. Wind blowing at 39 m/s alone is not enough to cause a tornado.
The wind speed over the house can be measured using an anemometer, which is a device that measures wind speed and direction. It consists of cups that spin in the wind, and the speed is calculated based on the rotation of the cups.
