Megan bailed out of her plane at an altitude of 8000 feet, fell freely for 15 seconds, and then opened her parachute. Assume that the drag coefficients are a=0.1 for a free fall and a=1.6 with a parachute. When did she land(in seconds)?
I changed your heading to physics, perhaps a physics tutor can shed light on how the drag coefficient works in here.
