We propose an analytic and numerical solution to the mechanical paradox of a sphere rolling upwards on two diverging inclined guides. This paradox challenges gravity, as the sphere appears to move uphill. Our approach develops a theoretical framework combining dynamics and energy conservation to explain this phenomenon. We derive and solve the equations governing the sphere's motion analytically and numerically under various conditions.
