Question
A skydiver weighing 163 Ibf (including equipment) falls vertically downward from an altitude of 4000 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 0.76| 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/s². Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachute opens. v(10) = i ft/s (b) Find the distance fallen before the parachute opens. x(10) = i ft (c) What is the limiting velocity vị after the parachute opens? VL = i ft/s
