Suppоse а dаmped mаss-spring system is gоverned by the differential equatiоn$$4y''+ c y' +9y = 0$$.Find the range of $$c$$ values for which the solutions of this equation are decaying oscillations, and then write down the general solution in terms of $$c$$, together with the amplitude $$A$$ and phase $$phi$$ (which are unknown constants).
