so mass doesn't factor into the equation??? a Jetski made from aluminum would need the same speed as from osmium?
I think so. At the apex of the loop gravity balances centrifugal force, Fg = Fc, when going the minimal speed necessary to get through the loop. Fg = m g, Fc = m v^2 / r. So mass m drops out of the equation.
