For the mechanical system, use complex impedances to derive the transfer function matrix connecting the input forces ui and uz to the output displacements yı and y2 of the two point masses. Known are m, c, and k. Use a) matlab and b) Simulink to plot the displacements yı(t) and y2(t) of the mechanical system shown based on the transfer function matrix derived in that problem. Known are m = 1.2 kg, c =14 N s/m, and k=180 N/m. The input forces are u1= 50*e- 31*sin(16t) N and u2 = 60/(t + 3) N. The initial conditions are zero. m m
