A skydiver bails out of an airplane at 2000m above mean sea level but cannot make his parachute work at first. The skydiver weighs 70 kg and is 1.7m tall. Determined the approximate velocity at which the skydiver will fall toward the earth. Base your calculations on the assumption that the skydiver lines flat with his arms by his side creating a circular cross-section of 0.26 m diameter. To answer this question you should examine carefully the plot of drag coefficient for a 2-d cylinder from your notes, and recognize that an iterative approach to solving this problem will be required. Make any reasonable additional assumptions you need but state them clearly. Base all of your calculations on properties of air at 2000 m in the ISA.
