This is the current problem that I am working on: "A volleyball is spiked so that it has an initial velocity of 14.1 m/s directed downward at an angle of 58.4 ° below the horizontal. What is the horizontal component of the ball's velocity when the opposing player fields the ball?"

I can draw out a picture perfectly fine for this, but for some reason I struggle with figuring out what I need and how to get it. For this problem it seems that I need to find V_{ox}because It said to find the horz. component when the ball is hit. I have a hint that says that the horz. acceleration, a_{x}, is zero. Does this mean that I need to use the equation: V_{x}^{2}= V_{ox}^{2}+ 2a_{x}X? I'm guessing I use that equation because there is no time value given.
