The Attempt at a Solution

So I assumed that there was no y component of velocity once the ball reaches it's lowest point. I believe this to be a very legit assumption. Even the scoring guidelines made this assumption.

The next thing that I did was use the velocity naught equation below that incorpates the velocity the acceleartion and the time in order to solve for the time

i didn't know the velocit though so i solved it using the equation velocity squared equation that incorporates the velocity naught the acceleration and the displacement which i knew all the terms and solved for the final velocity

i then solved for the time

i was then able to solve for the horizontal displacement sense the step before asked me to solve for the velocity naught in the x direction

The scoring guidelines confirmed my value i used for the horizontal velocity
