Momentum and Kinetic Energy

  1. Dec 4, 2004 #1
    I need help with this question:
    A cardinal of mass 3.60×10-2 kg and a baseball of mass 0.141 kg have the same kinetic energy. What is the ratio of the cardinal's magnitude of momentum to the magnitude of the baseball's momentum (p_c/p_b)?

    Consider that
    [tex]|\vec{p}|=m|\vec{v}|[/tex] and
    Can you figure it out from there?
