Two masses of 1 kg and 16 kg are moving with equal kinetic energy. The ratio of magnitude of the linear momentum is:

Answer»

`1 : 2`
`1 : 4`
`1 : sqrt(2)`
`sqrt(2) : 1`

SOLUTION :KINETIC energy, `K = 1/2 MV^2 = ((mv)^2)/(2m) = (p^2)/(2m) implies p = sqrt(2 m k) "or" p prop sqrt(m)`
`(P_1)/(P_2) = sqrt(1/16) = 1/4`.
