Physics average force need help

    Physics average force need help!!

    1. The problem statement, all variables and given/known data

    A coach is hitting pop flies to the outfielders. If the baseball (mass = 145 g) stays in contact with the bat for 0.09 s and leaves the bat with a speed of 84 m/s, what is the average force acting on the ball?

    2. Relevant equations

    Fnet=mv/ t

    3. The attempt at a solution
    Fnet= 145 x 84 / .09
    I got 135333.3 and this wa incorrect. I think I am using the wrong equation... Please help!!

    Problem looks like units, assuming you were supposed to give your answer in Newtons. If you want the force in Newtons, you need the mass to be given in kg.
