A mechanical system is governed by the following differential equation what is the homogeneous solution
Anika [276]

The ODE has characteristic equation

r^2+6r+9=(r+3)^2=0

with roots r=-3, and hence the characteristic solution

y_c=C_1e^{-3t}+C_2te^{-3t}

For the particular solution, assume an ansatz of y_p=ae^{-t}, with derivatives

\dfrac{\mathrm dy_p}{\mathrm dt}=-ae^{-t}

\dfrac{\mathrm d^2y_p}{\mathrm dt^2}=ae^{-t}

Substituting these into the ODE gives

ae^{-t}-6ae^{-t}+9ae^{-t}=4ae^{-t}=4e^{-t}\implies a=1

so that the particular solution is

\boxed{y(t)=C_1e^{-3t}+C_2te^{-3t}+e^{-t}}
