A skydiver weighing 184 lbf (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 12 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 13 vſ 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. (a) Find the speed of the skydiver when the parachute opens. v(12) = i 374.64 ft/s (b) Find the distance fallen before the parachute opens. x(12) = i 2225.55 ft (c) What is the limiting velocity v. after the parachute opens? VL = i 452.92 ft/s
