A paratrooper weighing 180 pounds (including equipment) falls vertically downward from an altitude of 5000 feet and open the parachute after 10 seconds of freefall. Assume that the resistance force of the air is 0.75v when the parachute is closed and 12v when the parachute is open, where the velocity v it is measured in feet / sec. to. a. Find the speed of the skydiver when open the parachute b. find the distance of fall before it opens the parachute. c. What is the limiting velocity vL after it is open the parachute? d. Determine how long the skydiver is in the air after the parachute opens. and. Plot the graph of velocity versus time from the beginning of the fall until the skydiver arrives down
