1.	Two bodies of masses 4 kg and 5 kg are moving with equal momentum. Then the ratio of their respective kinetic energies is
Answer» `4:5` `2:1` `1:3` `5:4` SOLUTION :KINETIC energy of a body, `K = (p^2)/(2M)`. where p is the momentum and m is the mass of the body. As `p_1 = p_2` (GIVEN) `:. (K_1)/(K_2) = (m_2)/(m_1) = 5/4`.
