 Quote by killerinstinct Ymax = Voy^2/2g. sub in and i get 2sqrt(2gYmax/2) to V0y-sqrt(2gYmax/2) sub in V0y and i get 2sqrt(2gYmax/2) to sqrt (2gYmax) - sqrt (2gYmax/2) some algebra help... how you simplify whats in bold... if i'm doing it right.... i get 2 to 1 ratio?? that doesn't sound right.
sqrt(gYmax) cancels from the numerator and denominator...

You should get: $$\frac{2}{\sqrt{2} - 1}$$
