Talk:Velocity of Bead on Brachistochrone

I never actually worked through the exercise so I don't actually know, but Simmons has $4 a v^2 = g \paren { {s_0}^2 - s^2}$ and not $4 a v^2 = g \paren {2 s s_0 - s^2}$.

This exercise needs to be worked through, and if Simmons is wrong, we need to raise an errata page. --prime mover (talk) 08:55, 26 September 2021 (UTC)
