Question

A cardinal (Richmondena cardinalis) of mass 4.50×10−2 and a baseball of mass 0.146 have the same kinetic energy. What is the ratio of the cardinal's magnitude of momentum to the magnitude of the baseball's momentum?

A man weighing 690 and a woman weighing 400 have the same momentum. What is the ratio of the man's kinetic energy to that of the woman ?
