A model that neglects air resistance predicts that a parachutist's speed will continue to increase by 9.8 m s−1^{-1}−1 every second after leaving an aircraft.
Explain why this prediction becomes increasingly unrealistic.
Describe qualitatively how the parachutist's actual velocity-time graph would differ before the parachute opens.
State the acceleration when the velocity-time graph becomes horizontal.
