A mass weighing 4 pounds stretches a spring 4/3 ft. The entire system is immersed in a fluid offering a damping force numerically equal to the instantaneous velocity. Beginning at t=0, an external force equal to f(t)=e^-t is impressed on the system. Determine an initial valued differential equation for the displacement of the mass from its equilibrium point at time t>0.
