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: [tex]\frac{2}{\sqrt{2} - 1}[/tex]
