5. The following equation describes free oscillation of a single-degree of freedom system: y" +26wny +wy=0, (0, w > 0) (a) Compute the general solution of the given equation when the damping co- efficient = 0, and the natural frequency w = 0.5; also, plot y(z) when y(0) = 1, y(0) = 1. (b) Compute the general solution of the given equation when the damping co- efficient C 2, and the natural frequency wn = 0.5; also, plot y(x) when y(0) = 1, y(0) = 1. =
