Calculate Horizontal Ball Drop at 41.3m/s Velocity

[pookisantoki]

A Major league pitcher can throw a ball in excess of 41.3m/s. If a ball is thrown horizontally at this speed, how much will it drop by the time it reaches a catcher who is 17.0m away from the point of release?
So Ay=-9.8
X=17m
t=?
Vox=0
V=41.3
y=(Vy^2-Voy^2)2g
I thoguht i would use this formula but wasnt sure how to figure Voy out since Vy=0...
Please help!

X=17m
t=?
Vox=0

Vox, the initial horizontal speed, is not 0, it is ____?
Also, ax = ____?

Can you fill in the blanks, and then use this information to find t?
