Homework Statement It seems simple, doesn't it? A bead starts from (0,1/2) and simply slides down the parabola y=(1/2)(x-1)[SUP]2 under gravity. The problem is to get its position rel. to origin in terms of time, ie. r = [x(t),y(t)]. Anyone into this? Homework Equations y' = x-1 = tan...

Thanks TT, But I can't find the "sub-forum index page" anywhere. Dev

You may be right TT. You may be right. Anyway, it's good to make some sort of contact at last. I've been playing around with the maths of a frictionless bead sliding down a parabola y=0.5(x-1)^2 . I got a messy result for its velocity but can't get the same using Hamiltonian mechanics. Anyone...

I still can't get a reply from anyone. Who is out there? Dev
