Can someone please explain the math in this question? It's confusing me.

Yes, that's the one. How do they get from (I'm trying my best to copy the notation here):
t(earth) = square root of 2h/2g(halfnia)
to
square root of 1/2 * (2h/halfnia)??
I just don't understand the math there. Maybe it's square roots that are confusing me.
I mean, how do you arrive there mathematically?
what about the different Vo of the 2 drops?
If I remember the question correctly, aren't the two objects launched horizontally, which would mean that voy would be zero for both of them? That allows us to ignore the y-direction velocity when determining the drop/flight time.
