A parachutist relies on air resistance (mainly on her parachute) to decrease her downward velocity. She and her parachute have a mass of 55.0kg and at a particular moment air resistance exerts a total upward force of 620N on her and her parachute. a) What is the weight of the parachutist? b) Draw a free-body diagram for the parachutist. Use that diagram to calculate the net force on the parachutist. Is the net force upward or downward? c) What is the acceleration (magnitude and direction) of the parachutist?
