My first post here! I signed up a few minutes to correct someone... then deleted my post when I realized I was on about something entirely different. Ahem.
Anyway, have a look at this diagram:

Particle P is suspended on an elastic string fixed at O, natural length = 'l', equilibium point is ( l + d ) below O, and 'x' is the distance the particle has been pulled down to.
Correct me if this is wrong. If you release P its motion will be simple harmonic, at least until it reaches the equilibrium point. But what happens to its motion after that? Once " OP < l ", its motion is like a normal particle under gravity but how does it move when " l < OP < l + d "?
Thanks in advance!
