A skydiver weighing 266 Ibf (including equipment) falls vertically downward from an altitude of 3000 ft and opens the parachute after 10s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.80 |v| when the parachute is closed and 12| v| when the parachute is open, where the velocityvis measured in ft/s. Use g = 32 ft/s?. Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachute opens. v(10) =| 205.95 ft/s (b) Find the distance fallen before the parachute opens. x(10) =| 1190.59 ft (c) What is the limiting velocity vz after the parachute opens? VL = 1 20.595 ft/s

NEEDED ONLY PART C
![Your answer is partially correct.
Askydiver weighing 266 Ibf (including equipment) falls vertically downward from an altitude of 3000 ft and opens the parachute after
10s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.80 | v| when the parachute is
closed and 12| v| when the parachute is open, where the velocity v is measured in ft/s.
Use g = 32 ft/s?. Round your answers to two decimal places.
