How much work has a pitcher done on a baseball

  1. Sep 28, 2010 #1
    1. The problem statement, all variables and given/known data
    A 0.140 kg baseball leaves a pitcher's hand at a speed of 30.0 m/s.
    If air drag is negligible, how much work has the pitcher done on the ball by throwing it?

    I don't even know where to start. I feel like if someone could help me find force i would be able to finish the problem
