Kinematics 2D: Horizontal Velocity of Spiked Volleyball

[Cheddar]

Homework Statement

A volleyball is spiked so that it has an initial velocity of 15m/s directed downward at an angle of 55degrees below the horizontal. What is the horizontal component of the ball's velocity when the opposing player fields the ball?

Homework Equations

horizontal velocity = velocity * cos(angle)

The Attempt at a Solution

15m/s * cos(55) = 8.6m/s
It seems like I'm missing something.

Really? I spent a long time on this thinking it was too easy to be correct...haha.
Thank you!
