Two bodies of different masses  m₁ and  m₂ have equal momenta. Their kinetic energies  E₁ and  E₂ are in the ratio

• A

  $\sqrt{{\mathrm{m}}_1} : \sqrt{{\mathrm{m}}_2}$

• B

  ${\mathrm{m}}_1 : {\mathrm{m}}_2$

• C

  ${\mathrm{m}}_2 : {\mathrm{m}}_1$

• D

  ${\mathrm{m}}_1^2 : {\mathrm{m}}_2^2$
