Some runners train with parachutes that trail behind them to provide a large drag force. these parachutes have a large drag coefficient, by design. one model expands to a rectangle 1.8 m square, with a drag coefficient of 1.4. a runner completes a 200 m run at 5.0 m/s with this chute trailing behind. how much thermal energy is added to the air by the drag force?
