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...
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...
