A skydiver of mass 81.5 kg jumps from a slow-moving aircraft and reaches a terminal speed of 54.9 m/s.
(a) What is her acceleration when her speed is 30.0 m/s?
(b) What is the drag force on the skydiver when her speed is 54.9 m/s?
(c) What is the drag force on the skydiver when her speed is 30.0 m/s?

how do i figure out this problem? All I got was teh R=(.5)pADv^2
maiking the first part a contant
R=Bv^2
R=mg
Bv^2=mg
