(a) Write a MATLAB function for the Adam-Moulton method of order 2. Input to the code should be: f (t, y), b, the number of subintervals (or steps) n. Output should consist of the value of y at last step (i.e., at t = b), and the graphs of both numerical and exact solutions over the interval [t_0, b]. Use the Runge-Kutta method of order 4 to determine the starting values. As predictor for the scheme, use the Adam-Bashforth method of order 2. (b) An object of mass 8 kg is given an initial upward velocity of 20 m/sec and then allowed to fall under the influence of gravity. Assume that the force in newtons due to air resistance is -16v^2, where v is the velocity of the object in m/sec. Use your code from part (a) with n = 100 to approximate the velocity v of the object after 10 seconds. (gravitational acceleration g = 9.81 m/sec^2)
