Answer: it depends on how high up the skydiver is jumping from.
Explanation: Examples: if the skydiver jumps from 6000 ft with a 900N air resistance it equals 10 as its acceleration. If they drop from 5500 ft with 900 air resistance then it is 7.77 acceleration.
More Examples:
4500 ft, 900N = 0 acceleration
3000 ft, 900N =2.2 acceleration
2900 ft, 900N =6.66 acceleration
1500ft, 900N = 0 acceleration
It may also depend on the Faix, but I hope this will help you!
