4. Consider a mass-spring system where M = 2 and k = 8. (a) Express the general solution for this system. (You may have to refer to your ME 391 textbook.) (b) Say that M = 2 kg and k = 8 N/m, calculate the natural frequency expressed in rad/s and in Hertz. (@=2, T = 1/.) (c) Provide the specific solution when y(0) = 1 and y'(0) = 0. (d) Using Matlab, plot y vs t for t = (0,5). Provide a title and label the axes. 4. Consider a mass-spring system where M = 2 and k = 8. (a) Express the general solution for this system.
