Thus we have found the speed required to complete a loop the loop of radius \(r\). For example, if the loop had a 4 metre diameter (2 metre radius) then the velocity required to complete the loop would be \(v = \sqrt{5\times g\times 2}=\sqrt{10g}\approx 9.9\). For convience we can approximate \(\sqrt{5gr}\) as \[\sqrt{5\times 9.81\times r}=\sqrt{49.05r}\approx 7\sqrt{r}.\] — Many thanks to
