I'm new to using Maple, so this is really confusing me. This is for my differential equations class. I'm suppose to solve it using methods like the ones in the pdf I attached, and the by using dsolve() to verify the solution from the first approach.
Q.) A woman bails out of an airplane at an altitude of 10,000 ft, falls freely for 20 s, then opens her parachute. How long will it take her to reach the ground? Assume linear air resistance pv ft/s^2, taking p = 0.15 without the parachute and p = 1.5 with the parachute. (Suggestion: First determine her height and velocity when the parachute opens.)
