A skydiver weighing 257 lbf (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 15 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.77 | V| when the parachute is closed and 11 | 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(15) ft/s (b) Find the distance fallen before the parachute opens. x(15) i ft (c) What is the limiting velocity vų after the parachute opens? VL = i ft/s
