(b) Consider a massless string of length moving in air. The string is fixed with a pin on one end and a mass at the other. The equation of motion of the simple pendulum with a linear drag is 9+9+ sin9=0, t>0 me where c/ml = 0.4 rad /s' (c is the damping coefficient due to air drag),g=9.81 m/s² and (=2 m. Let 9(0)= rad and 9 (0) = 0.25 rad/s. Use the trapezoidal method to calculate I the angle versus time,9(t), and the angular velocity velocity versus time, 9(t). Choose the time step and show your calculations for the first two steps.
