I NEED HELP WITH B AND D!

3. A single degree-of-freedom, linear, mass-spring-damper system has a mass of 5 kg and a spring constant of 300 N/m. a. What is the value for critical damping for this system? b. Using Matlab, plot the eigenvalues as c ranges from 0 to 1.5ce. (This plot will look similar to Figure 2.38 in the text.) If c = 50 N. sec/rn, is the system underdamped, overdamped, or critically damped? What is the logarithmic decrement? c. d. Using Matlab, plot the system response for time on [0, 2 sec for four values of damping: c = 5 N.sec/m, c = 50 N.sec/m, c = 75 N.sec/m, and c = 90 N.sec/m. Assume xo = 2 m and xo = 8 m/s
