Kinetic Energy question

  1. Feb 12, 2010 #1
    1. The problem statement, all variables and given/known data

    Explain how a golf ball and a football can have the same kinetic energy even if their masses are different.



    2. Relevant equations

    None.


    3. The attempt at a solution

    A golf ball and a football can have the same kinetic energy even if their masses are different because kinetic energy is a quadratic function of speed.

    This is a new topic and I missed a class or two on it so it may be a super easy question but I just wanted to see what you guys and gals think! Thanks!

    Well in essence yes, since Ek=1/2mv2, they can have the same Ek if they move with different speeds.
