The Uphill Roller Experiment and a Variation on Theme
De Luca, R.; Ganci, S.
European Journal of Physics, v32 n1 p101-106 Jan 2011
We propose an analytic solution to the problem of the mechanical paradox consisting of a sphere rolling upwards on two diverging inclined guides as devised by Gardner. The presence of an unstable equilibrium point is highlighted and the analytic solution is found by means of elementary calculus concepts. (Contains 4 figures and 3 footnotes.)
