3. Under everyday conditions, air drag is proportional to v². Specifically, Fa = Dv² (where D is a constant that depends on air density, the cross-sectional area, and the object's shape). Thus, the faster an object is going the greater the air drag. When an object is falling straight down, there is a speed at which the net force on the object will be zero. This speed is known as TERMINAL VELOCITY. Apply the formula you derived for Fnet to the situation where an object has reached terminal velocity (Fnet = 0) to solve for D. Let v = v7 (terminal velocity) and express your answer in terms of m, g, & vr. D= 0.03028
