The force F exerted by the wind on a window varies jointly with the area A of the window and the square of the velocity of the wind. If the force on a window of 25 square feet is 20 pounds when the wind velocity is 4 mph, find the force on a window of 22 square feet when the wind velocity is 5 mph.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
