Simple Harmonic Motion Problem 4

[ehild]

It's horrid alright, but I can't find a flaw. Do you see one?

I do not know how you got it, but it does not look to give the same A as I got, both from energy and from SHM. Can you show your result?

Have you the change of elastic energy properly taken into account?

No, I had that wrong. Thanks!

Have you got the same result as me in #34?

My "assumption", which you refer to below, is that at the very beginning of the problem, immediately before the mass begins to fall, at that moment the system is at rest and therefore in equilibrium.

You seem to be assuming that also.

I was thinking you are taking t = 0 at the moment when the particle strikes with the cage.
