Yeah, that makes more sense. Thanks!

Right, so the equilibrium position is 0 and the displacement is 40? So the extra 20cm is used to solve the other questions? It's not used in the string stiffness question? I think I'm starting to confuse myself now, lol.

Oh, so equilibrium would be 0cm? As the weight pulls it out of equilibrium, so then the displacement would be 60cm?

Right so for K I have, 981. F = M.A, 2kg x 9.81 = 19620 N K = F/x, 19620/20 = 981. Is that right?

I've been set this question by my tutor and I'm having difficulty doing it. A mass of 2 kg is hung from the lower end of a vertical spring and extends it by 40 cm. The mass is now pulled down a further 20 cm and is then released from rest so that it oscillates about the equilibrium position...

Kirk has improved a lot in recent times. He got very sloppy and relied on his Wah, but he's definitely got himself back up to scratch. I'm going to have to go with Joe Satriani. I've seen him live a few times and his control and mastery of the guitar is unreal. It may as well be extra limb on...
