The bodies A and $B$ are oscillating in free vibration governed by the following differential equations:

equation $A$ :

$5x^{}+2x^{}+3x=0$;

equation B:

$2x^{}+x^{}+2x=0$

A and $B$ are subjected to the same initial conditions where $x(0)=0$ and $v(0)=0\mathrm{.}1\frac{m}{s}$ over the time interval $0$ to $50$ s with an increment of $0\mathrm{.}001$ s $.$

Use ode $45$ to find the responses of A and $B$ oscillating motion.

Plot the displacements of A and $B$ on the same figure. Write axes titles, graph title, and legend.

Plot the velocities of A and $B$ on another figure. Write legend.

The mass of $B$ is increased to match the mass $A($first coefficient of differential equation$).$ Find the new response of $B$ after the mass modification.

Compare the displacements and velocities of $B$ before and after the mass modification by plotting the displacements on one figure and the velocities on another figure. Write legend.

Using subplot, plot the displacements and velocities of A and $B($before and after the mass increase$).$ Write title for each graph.
