Does Launching a Projectile at 45 Degrees Alter Its Initial Velocity?

If a projectile is launched horizontally, and has initial velocity X, then is launched with the same force from an angle, let's say 45 degrees, would the initial resultant velocity (at time=0) still be X?

Let's say you fire something at 0 degrees with a velocity of 500m/s in the horizontal direction. Do you believe it will be traveling at 500m/s in the horizontal direction if you fire the same canon and projectile at 89 degrees?

 

[tuyop]

Well, that makes my question sound REALLY simple. And no, I think it would go 500m/s at 89 degrees.

 

[Pengwuino]

Yes, no matter what angle you fire this projectile, it will always exit that cannon at 500m/s. The only thing that will change is the horizontal and vertical components

Yeah, that's what I thought. Thank you so much.
