A skydiver weighing 180lb (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 10 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude \(0.75|v|\) when the parachute is closed and is of magnitude of \(12|v|\) when the parachute is open, where the velocity \(v\) is measured in ft/s. 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 \(v_L\) after the parachute opens?
