Homework Help: Change of Momentum

  1. Feb 23, 2008 #1
    1. The problem statement, all variables and given/known data

    An object of mass 4.5 kg is projected into the air at a 53° angle. It hits the ground 3.6 s later. What is its change in momentum while it is in the air? Ignore air resistance.

    2. Relevant equations

    P = mv V=Ft/m

    3. The attempt at a solution

    I'm not sure how to find the velocity for this question, otherwise I know how to find the answer.
