(b) Consider the case where fo = 0, ie, there is no external harmonic force, the intial displacement is = [0.0.5. 0.5)?ms 1 and there is zero initial velocity. Using the decoupling process, find the displacement histories for the system. What do you notice about which modes are active in the displacement solution? x =
