Solving Equations - Projectile Motion

Using these 2 equations:


1) x = (vox * t) + (½ ax * t^2) = (vo * t)


2) y = (voy * t) + (½ ay * t^2) = (-½ g * t^2)


Show that this equation is correct:


vo = D ( g / ( 2 H ) )^½

For projectile motion, equation 2 does not reduce to (-1/2 g t^2), you need to include voy. Equation 1 has a typo in right-hand term, should be vox. Without these corrections, height H = 0 and the solution is infinite!
