Times of flight for projectiles

[ThomasMagnus]

Is the time it takes for a projectile to hit the ground the same for the x and y axis' ?

For example, if you are given the range of a projectile or told that it will hit a fixed point, will it have the same time of travel for x and y?

If you know that it hits a fixed Point or are given the range, I assume that all of these formulas will correctly solve for t and that it will be the same.

Vx=Dx/t

Dy=(Voy)(t) + 1/2at^2

Vfy= Voy + at

Is this correct?


Thanks

Yes, the flight time in both X and Y directions will be the same.

If it wasn't, it would imply it continued flying in one direction once the other had hit the ground - so the X has impacted the ground but the Y is still in the air. Silly isn't it.
