Two bodies of masses M1 and M2 have equal energies.If P1 and P2 are their respective momentum,compute P1/P2.
E1=E2 ⟹ m1v122=m2v222 ⟹ v1v2=m2m1,E_1=E_2\implies\frac{m_1v_1^2}{2}=\frac{m_2v_2^2}{2}\implies \frac{v_1}{v_2}=\sqrt{\frac{m_2}{m_1}},E1=E2⟹2m1v12=2m2v22⟹v2v1=m1m2,
p1p2=m1v1m2v2=m1m2⋅m2m1=m1m2.\frac{p_1}{p_2}=\frac{m_1v_1}{m_2v_2}=\frac{m_1}{m_2}\cdot \sqrt{\frac{m_2}{m_1}}=\sqrt{\frac{m_1}{m_2}}.p2p1=m2v2m1v1=m2m1⋅m1m2=m2m1.
