A parachutist and her parachuting equipment have a combined mass of 101 kg. Her terminal velocity is 5.30 m/s with the parachute open. Her parachute has a cross-sectional area of 35.8 m^2. The density of air at that altitude is 1.23 kg/m^3. What is the drag coefficient of the parachutist with her parachute? (The answer should be 1.60)
