horizontal union movement?

fired @ 60 m / s compressed from a horizontal gun, tennis ball hits a base meters 80th I have appointed the initial vertical speed to 0 and how long the ball will be in the air with the help of the equation for distance / speed = 80 m/60 MSS = 1.3 seconds digits as I noticed how high the weapon was out of the ground?

You're on the right track. It takes to fall 1.3 seconds. So use d = (2.1) at ^ 2 + ut. 0.5 x 9.8 x 1.3 ^ 2 = 8.28 meters.
