Matlab about Bungee Jump

Help me with the sentense c in matlab

Problem 1) A bungee jumper jumps from a mountain with the downward vertical velocity v described by the mathematical model: dv/dt = g − (cd/m)*v^2 (see the picture), where m is the mass of jumper and cd is called drag coefficient.

a) Suppose that the jumper is initial at rest, find analytically the expression of v.

b) Let g = 9.8(m/s2 ), m = 68.1(kg), cd = 0.25(kg/m) and the jumper is initial at rest, establish the table to compute the velocity of the jumper for the first 10 seconds with step size h = 1(s) by using modified Euler’s and Runge-Kutta’s method. Compare the results to the exact values found in a).

c) Using the result of a) and the bisection method, the secant method to determine the drag coefficient for a jumper with the weight of 95(kg) and the velocity v = 46(m/s) after 10 seconds of fall until the relative error is less than 5%(Guess the isolated interval containing root)

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.
