A parachutist relies on air resistance (mainly on her parachute) to decrease her downward velocity. She and her parachute have a mass of 55.5 kg and air resistance exerts a total upward force of 660 N on her and her parachute.
(a) What is the combined weight of the parachutist and parachute?
(b) Draw a free-body diagram for the parachutist.
(c) Calculate the net force on the parachutist.
(d) Is the net force upward or downward?
(e) What is the magnitude of the acceleration of the parachutist?
(f) What is the direction of the acceleration?
