A cardinal (Richmondena cardinalis) of mass 4.50×10−2 and a baseball of mass 0.140 have the same kinetic energy. What is the ratio of the cardinal's magnitude of momentum to the magnitude of the baseball's momentum?(adsbygoogle = window.adsbygoogle || []).push({});

i derived an equation of 1*p^2/2m and im not sure where to go from there.
