There is a speed equation of the bungee jumping phenomenon as below. gcd v(t) = tanh m Look for the jumper mass if the cool speed after 4 seconds is 36 m/s with the air friction constant value cd = 0.25, and the gravitational acceleration g = 9.8 a. Make the plot of the equation with iterations at least 100 times. (use matlab) b. Turn the equation above into a new function that can be searched for roots. the equation of the function, then determine the root of the new equation using the bracket method (bisection or false position). (use matlab)
