Homework Help: Projectile Motion

  1. May 20, 2008 #1
    1. The problem statement, all variables and given/known data

    i hit a golf ball of mass 0.045kg with an avg. Force of 2.5x10^3 N over a short time interval of 1.0 x 10^-3 s at an angle of 30 degrees with respect to the horizontal. neglect air resistance and assume a level course.

    What is the speed of the ball immediately after contact?


    2. Relevant equations

    Ft=mv


    3. The attempt at a solution


    v=Ft/m

    2500x.001/.045

    v=55.6m/s?

    If that is the wrong answer why? If that is right can someone further explain it to me?

    It looks fine to me. What do you need explaining?
