I need help solving this problem in MATLAB. Consider the thin rod of length l moving in the x - y plane as shown:

Problem 1 Consider the thin rod of length I moving in the x-y plane as shown in Fig. P23.15. The rod is fixed with a pin on one end and a mass at the other. Note that g = 9.81 m/s2 and I = 0.5 m. This system can be solved using Let (0) = 0 and 6(0) = 0.25 rad/s. Solve using any method studied in this chapter. Plot the angle versus time and the angular velocity versus time. (Hint: Decompose the second- order ODE.) Problem 2 Use the shooting method to solve 7-2 d. y + x = 0 With the boundary conditions y(0-5 and y(20)-8 Problem 1 Consider the thin rod of length I moving in the x-y plane as shown in Fig. P23.15.
