A wind with speed $\displaystyle 40 \mathrm{~m} / \mathrm{s}$ blows parallel to the roof of a house. The area of the roof is $\displaystyle 250 \mathrm{~m}^2$. Assuming that the pressure inside the house is atmospheric pressure, the force exerted by the wind on the roof and the direction of the force will be : $$\left(P_{\text {air }}=1.2 \mathrm{~kg} / \mathrm{m}^3\right) $$
