Problem
Use bisection method to solve for mass, m, in the
bungee jumper mathematical model. Assume
v=36, t=4, g=9.81 and ca=0.25. Use initial
guesses of xl-50 and xu=200. Tabulate the
values for xl, xu, xr, and the approximate percent
relative error for each iteration. Note also the signs
of f(xl), f(xu) and f(xr). Use a stopping criterion of Es
= 0.5%.
