Homework Help: Newtons law question.

  1. Oct 7, 2008 #1
    Have a difficult time on where to start here, iv'e looked over the book, and my notes, and I believe the question is more basic than given, Am I thinking too in depth here? Help please!

    A 0.110 kg baseball, traveling 34.0 m/s, strikes the catcher's mitt, which recoils 14.0 cm in bringing the ball to rest. What was the average force (in newtons) applied by the ball to the mitt?

    From the velocity and distance to stop, you can get an average acceleration. Then given that acceleration and a mass, you should be able to get an average force.

    Welcome to PF.

    F = m*a

    So all you are missing is a.

    But a can be found fairly simply by V2 = 2*a*x

    For kinematic equations:
