Question

A skydiver weighing 164 lb (including equipment) falls vertically downward from an altitude of 6000 ft and opens the parachute after 19 s of free fall. Assume that the force of air resistance is 0.74 v when the parachute is closed and 10 v when the parachute is open, where the velocity v is measured in ft/s.
Use g = 32 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?
