After the spring-mass is in equilibrium, a force is applied then released at t0 and the spring-mass system is set into motion. For a certain period of time the spring-mass will move around the x0 equilibrium position until the restoring from the spring has balanced the gravitational force.
Are my two equations correct? I guess I'm having trouble accounting for the gravitational force and the forcing term in the DE. Otherwise, it would be a simple homogeneous equation with x = A cos(w0t).
