Homework Help: Kinematics in 2-D

  1. Jul 30, 2009 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations
    horizontal velocity = velocity * cos(angle)

    3. The attempt at a solution
    15m/s * cos(55) = 8.6m/s
    It seems like I'm missing something.
