An aircraft has a wing area of 20 m2 and whose wings resemble the NACA 23012 with no flaps and is flying horizontally (0° angle of attack) at a constant speed of 250 km/h. To gain height the pilot adjusts the controls so that the angle of attack becomes 10°. Take the density of the air as 1.23 kg/m3. Determine the total power required to execute this action at the same constant speed.

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.
