Momentum and Kinetic Energy

  • #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
[tex]E_{K}=\frac{1}{2}mv^2[/tex]
Can you figure it out from there?
