Catapult final (impact) velocity

[Havenater23]

Homework Statement

I'm doing a catapult project and I have to calculate a few pieces of information.
The initial velocity of the release (horizontal and vertical components) , the time of the highest point, and velocity of impact of the object.

I know how to do all of these except find the velocity impact of the object. This is all on a horizontal plane, and I know the X initial horizontal velocity will stay the same, but how do I figure out the y initial vertical velocity?

I know that if I find those two components at the end, I can use Pythagoras to solve it.

The Attempt at a Solution

Thanks, in advance

If you know the total time a projectile is in the air, you can figure out how long it took to get to the top of it's trajectory (it's highest point) by just dividing by 2. [The projectile will take the same amount of time going up as down]. Then just solve for v_0 by using kinematic equations.
