The following are the equations of motion of the two-mass suspension model shown in Figure 3. mx = k(x-x) + C(x-x) mx = k(x-x) C (x-x) + k (y - x) Develop a Simulink model of this system to obtain the plots of x and x. The input y(t) is a unit step function, and the initial conditions are zero. Use the following values: m = 250 kg, m = 40 kg, k = 1.5 x 104 N/m, k = 1.5 x 105 N/m, and c = 1917 N-sec/m.
