A bomb of mass 9kg initially at rest explodes into two piece of masses 3 kg and 6 kg. The kinetic energy of the 3 kg mass is 216 J. The kinetic energy of the 6kg mass will be :-

Answer

`108.00`

Explanation

`p^(2) = 2m_(1)k_(1)`
`p^(2) = 2m_(2)k_(2)`
`implies m_(1)k_(1) = m_(2)k_(2)`
`k_(2) = (m_(1)k_(1))/(m_(2))`
`k_(2) = (3xx21.6)/(9) = 108 J`.
