The velocity v of a falling parachutist is given by where g = 9.81m/s . For a parachutist with a drag coefficient c = 16kg/s, compute the mass m so that the velocity is v = 20m/s at t = 8s. Use the following initial guess - [mlower , mupper ] = [5, 130] for bracket methods, minitial = 50 for open methods. If there is no specified relative error percentage or number of iterations, please use relative error percentage = 0.0001% and maximum iterations= 50.

o With the Modified Secant method, - with 8 = 0.1, iterate until 3 = 0.1% then save [root, the number of iteration]on EX2_9.dat, - with 8 = 0.1, iterate 10 times then save [root, Ea] on EX2_10.dat
