The air is less dense at higher elevations, so skydivers reach a high terminal speed. The highest recorded speed for a skydiver was achieved in a jump from a height of 39,000 m. At this elevation, the density of the air is only 4. 3 % of the surface density of air at 20 ∘c. Estimate the terminal speed of a skydiver at this elevation. Suppose the mass of the skydiver is 75 kg and the cross section area of the skydiver is 0. 72 m2. You could consider the diver as a cylinder traveling sideways for this problem.
