The drag constant, D for an object falling through air depends on the position. The position basically determines the effective cross-sectional area. Determine the terminal speed of a 62 kg skydiver falling through the air in a feet-first position. The drag constant for this position is 0.15 kg/m. Hint: vt = √(mg/D)
