Homework Statement
A cardinal (Richmondena cardinalis) of mass 3.80×10−2 kg and a baseball of mass 0.144 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 = ?
attempt :
P_c / p_b = M_c*V_c / M_b*V_b
M_c / M_b = 19/72 ; their ratio
so their V has to be a ratio of = V_c/V_b = 72/19.
not sure what after this.
