3.53 Consider the spring-mass-damper system in Figure P3.5, with the parameter values given by m, = 20 kg, m2 = 30 kg, k = 2000 N/m, k, = 3000 N/m, c= 75 N s/m. Assume zero initial conditions. (a) Assume that f = 0 and y = 0.5 m (step input). Plot the displacement x2 versus time by MATLAB (b) Assume that f = 458(1) N:s (impulse input) and y=0, where 8(t) is the Dirac delta function. Note that the force of the spring k, is zero in this case. Plot the displacement x2 versus time by MATLAB. Hint: In parts (a) and (b), you can obtain the corresponding transfer functions first. x ky W m m2 1 Figure P3.5
