Potential energy=mass*acceleration due to gravity*height
= 8 000 000 * 9.8 * 50
= 3.92 * 10^9
PE = mgh₁ - mgh₂= 12.5J
h₁ = ?
h₂ = 0
h₁ = PE / mg = 12.5 / 9.8
Assuming that the pressure inside the house is at atmospheric pressure, the force on the window is approximately 1378 Newtons.
Given the data in the question;
- Area of the window;
- Velocity of wind;
Force on the window;
<h3>Force</h3>
Force is an influence that can cause the change of motion of a particle or object. Also, force normal to the area of a surface is equal to pressure multiply by the area of that surface.
Where P is pressure and A is area of the surface.
Also, we know that;
Where is density of air, approximately( ) and V is velocity.
Hence
We substitute our values into the equation above
Therefore, Assuming that the pressure inside the house is at atmospheric pressure, the force on the window is approximately 1378 Newtons.

Answer:
The resulting net force is 650N
Explanation:
The force caused by air resistance against the plane's motion is called the Drag force. It acts against the motion of the plane. However, tailwinds push the plane from its tail and they apply a force is the direction of the moving plane.
The resulting force is the sum of the two forces; 450N +200N = 650N
