Problem 3 (modified from problem 5.1) Use bisection to determine the drag coefficient needed so that a 95kg bungee jumper has a velocity of 46m/s after 9s of free fall. Note: the acceleration of gravity is 9.81m/s2. Start with initial guess of x1=0.2 and xu=0.5. v(t)=cdgmtanh(mgcdt) 1) Use graphical method to roughly determine the root of drag coefficient. Use 'Data Tips' tool to pick up the value. Note: use xl abel and y label command to properly label x and y axes. 2) Do it by hand on paper: perform bisection algorithm for the first iteration, and answer following questions a. What is the new estimate of the root xr ? b. Will the new root replace the x1 or xu ? Why? c. What is the approximate relative error after the first iteration (please use x1 as the initial guess of the root)? 3) If you would like to achieve a desired error Ea,d=0.001 (it is not a percentage value), how many iterations do you need? 4) Use bisect () function to find the root
