A woman bails out of an airplane at an altitude of 12,000 t, falls freely for 24 s, then opens her parachute. How long will it take her to reach the ground? Assume linear air resistance v R/s, taking p=0.15 without the parachute and p=1.5 with the parachute. (Suggestion: First determine her height above the ground and velocity when the parachute opens.) It will take her 402 seconds to reach the ground (Round to the nearest whole number as needed) dave Ch
