F = MA

  1. Feb 16, 2016 #1
    1. The problem statement, all variables and given/known data
    A 56 g tennis ball is accelerated at 1000 m s-2 to reach its service velocity. Calculate the average resultant force required to accelerate the ball.

    2. Relevant equations
    F = MA

    3. The attempt at a solution
    Mass = 0.56g = 0.056kg
    Acceleration = 1000m/s2

    0.056 x 1000 = 56N.

    Is this correct? I know this is how to calculate the resultant force but it asks for the average? Does that change anything.

    Do you have any additional information to average?

    Nope, that's the whole question.

    ... and, that is the whole answer.

    Ok thanks, I thought maybe gravity would have some impact here.
