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 50 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.
