$[$Ch$3$ : $3]$ The parameter of a single$-$degree$-$of$-$freedom system are given by $m=5kg,c=8N.\frac{s}{m},$ and $k=30\frac{N}{m}.$ Using MATLAB $/$ OCTAVE, plot the response, $x(t)$ on the same graph for the following initial conditions: $($include all syntax $/$ codes in the answer sheet$)$

a$.,xo=10cm$ and $v_0=100c\frac{m}{s}$

b$.x_0=10cm$ and $v_0=-100c\frac{m}{s}$
