Use bisection method to determine the drag coefficient needed so that a 95-kg bungee jumper has a velocity of 46 m/s after 9 s of free fall. Start with initial guesses of xl = 0.2 and xu = 0.5 and iterate until the approximate relative error falls below 5%. Note: The acceleration of gravity is 9.81 m/s2. (Round the final answer to four decimal places.)
