A parachutist relies on air resistance (mainly on her parachute) to decrease her downward velocity. She and her parachute have a mass of 51.1 kg and air resistance exerts a total upward force of 657 N on her and her parachute. What is the magnitude of the acceleration of the parachutist?

Question

anonymous · Answer

weight - air resistance = ma 
 where "m" is the mass of the parachutist and "a" is the net acceleration.
on solving the equation, you will get the net acceleration.

do you get it?

Do I need to convert the newtons to kg?

anonymous · Answer

no. air resistance here is equal to 675N
and weight is equal to mass*g
