(a) Obtain the equations of motion of the system shown in Figure. Assume small angles. The spring is at its free length when θ1 = θ2 = 0.
(b) For the values m1 = 1 kg, m2 = 4 kg, k = 10 N/m, L1 = 2 m, and L2 = 5 m, use MATLAB to plot the free response of θ1 if θ1(0) = 0.1 rad and θ1 (0) = θ2 (0) = θ2 (0) = 0.
