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

Options:

Answer:

Solution:

$K.E. = \frac{p ^{2}}{2 m} ∴ \frac{K _{1}}{K _{2}} = \frac{p _{1}^{2}}{2 m _{1}} \times \frac{2 m _{2}}{p _{2}^{2}} = \frac{m _{2}}{m _{1}} = \frac{16}{9} ∴ \frac{m _{1}}{m _{2}} = \frac{9}{16}$
