A wind with speed $40\,\text{m}\,\text{s}^{-1}$ blows parallel to the roof of a house. The area of the roof is $250\,\text{m}^2$. 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: ($\rho_{\text{air}} = 1.2\,\text{kg}\,\text{m}^{-3}$)
