WebFind the terminal velocity of an 85-kg skydiver falling in a spread-eagle position. Strategy At terminal velocity, F net = 0. Thus the drag force on the skydiver must equal the force of gravity (the person’s weight). Using the equation of drag force, we find mg = 1 2 ρCAv 2. Thus the terminal velocity v t can be written as v t = 2 mg ρCA. 5.21 WebVelocity of a falling object. An object falling through viscous medium accelerates quickly towards its terminal speed, approaching gradually as the speed gets nearer to the terminal speed. Whether the object experiences turbulent or laminar drag changes the characteristic shape of the graph with turbulent flow resulting in a constant ...
