# Thread: Projectile Motion Problem

1. ## Projectile Motion Problem

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 Vox because It said to find the horz. component when the ball is hit. I have a hint that says that the horz. acceleration, ax, is zero. Does this mean that I need to use the equation: Vx2 = Vox2 + 2axX?
I'm guessing I use that equation because there is no time value given.

So does this mean that Vx = cos(58.4 deg)? Because I think the initial velocity value they give me might have something to do with it.

|V| is 14.1 m/s

so Vx = 14.1 cos(58.4 degrees)
