Wind with a velocity 100km h^(-1) blows ...

Wind with a velocity `100km h^(-1)` blows normally against one of the walls of a house with an area of `108 m^(2)`. Calculate the force exerted on the wall if the air moves parallel to the wall after striking it and has a density of `1.2 kg m^(-3)`.

To solve the problem, we will follow these steps: ### Step 1: Convert the wind velocity from km/h to m/s The wind velocity is given as \(100 \, \text{km/h}\). To convert this to meters per second (m/s), we use the conversion factor \( \frac{5}{18} \). \[ V = 100 \, \text{km/h} \times \frac{5}{18} = \frac{500}{18} \approx 27.78 \, \text{m/s} \] ...
