Homework Help: Relating Kinectic energy and momentum

  1. Jul 9, 2008 #1
    1. The problem statement, all variables and given/known data
    Relate Kinetic energy and momentum, i.e. show that K=pv/2

    2. Relevant equations

    3. The attempt at a solution[/b
    I don't know what equation to begin with to show this!

    Start with the definition of kinetic energy: K = 1/2 * m * v^2

    Does that help? Also, it would be good to know the definition of momentum (p).

    ok I got it I thought it required more than that. You have (1*(MV)*V)/2. MV being your momentum, Thank you!!
