Homework Help: Net Accelleration

  1. Oct 5, 2008 #1
    1. The problem statement, all variables and given/known data
    I am having some trouble finding out exactly how I could find net acceleration.
    I know how to use it for finding force of drag, and other formulas, but for a project I need to actually find the net acceleration of me throwing a baseball.
    This is a sample problem, that I need to know how to solve, and I'll use the 'method' to solve for my actual project:

    Angle from horizontal (theta): 10degrees
    Force of throw: 300N
    Mass of ball: 2kg

    2. Relevant equations
    Fdrag = bv
    Net acceleration = gsin(theta)
    Sum of all forces = mg-ma

    3. The attempt at a solution

    I know how to find the force of drag, which is ultimately what I need...
    (assuming I actually know net accleration is 5m/s/s)
    Fdrag = 4.8N

    But I want to know how to find net acceleration.
