Kinetic Energy & Momentum

Two bodies are having kinetic energies in the ratio 16: 9. If they have same linear momentum, the ratio of their masses respectively is:

Show answer and solution

Answer: (c)

Equal momentum: $m \propto \frac{1}{K}$ .
$\frac{m_1}{m_2} = \frac{K_2}{K_1} = \frac{9}{16}$
So the answer is (c) $9 : 16$ .
