Considers the following dynamic systems.

I$)$ Initial conditions: when t $=0,$ x $2=1,$ v $1=-1,$ v $2=1,$ x$1=-1.$

II$)$ Time span: t $=0$ to $25$s$.$

III$)$ Consider M $1=1,$ M $2=2,$ B $1=2,$ B $2=1,$ K $1=1,$ K$2=2,$ and f$=0.$

Write a Matlab code using the $$initial$$ command to find the system response
