Solve the all parts of given question:
Question: A parachutist relies on air resistance (mainly on her parachute) to decrease her downward velocity. She and her parachute have a mass of 53.5kg and air resistance exerts a total upward force of 700Non her and her parachute.
Part A: Calculate the net force on the parachutist?
Part B: What is the magnitude of the acceleration of the parachutist?
I need help to find the magnitude of the acceleration of the parachutist.
