How do you calculate final velocity from a projectile shot from an air cannon? I have the initial velocity, but I can't seem to find the final, or average velocity. Please help

If it is project from cannon it has horizontal velocity Ux that is given and Uy=0.. In projectile Ux will remain same and Vy=Uy+at i.e., Vy=0+(-gt) therefore final velocity will be √(Ux)^2+(-gt)^2 ...
