What is the terminal velocity of a 72-kg skydiver in a spread-eagle position? Assume that the effective area of the diver facing against the air is 0.65 m², air density 1.21 kg/m³ and drag coefficient 0.95. (Note: What is terminal velocity? Drag force opposes the weight or the force causing the object to move and is proportional to the square of the velocity for large objects like a skydiver. As the velocity increases at some velocity the opposing force will balance out the force causing the motion. Hence no net force after that and as a result the velocity does not increase any further. This velocity is called the terminal velocity.)
