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.

W = 20 m
Hint 1: To calculate the drag force split the fuselage into 4 parts: front hemisphere,
cylindrical body, vertical stabilizer, back hemisphere. Model the front and back hemispheres
as flow over a sphere. For simplicity treat the cylindrical body and vertical stabilizer as flat
plates
Hint 2: Use Ca vs Reynolds number graphs for sphere and flat plate. If your Reynolds number
is greater/smaller than the Cd vs Reynolds graph range, you can instead use the
greatest/smallest number available on the graph.
