A skydiver weighing lb (including equipment) falls vertically downward from an altitude of ft and opens the parachute after s of free fall. Assume that the force of air resistance is when the parachute is closed and when the parachute is open, where the velocity is measured in ft/s.
Use ft/s2. Round your answers to two decimal places.
(a) Find the speed of the skydiver when the parachute opens.
(b) Find the distance fallen before the parachute opens.
(c) What is the limiting velocity after the parachute opens?
