$($ Please USE MATLAB$)$ The spring$-$mass system of $150$ kg mass, stiffness of $1500$ N$/$m$,$ and damping coefficient of $200$ Ns$/$m is given an initial velocity of $10$ mm$/$s and an initial displacement of $5$ mm$.$ Calculate the form of the response and plot it for as long as it takes to die out. How long does it take to die out?
