Here initial momentum 
. Since no external force exists, hence momentum must remain conserved 
, 
As two fragments of mass mass 
each are moving with speed 
each at right angles,
.
The mass of third fragment is 2 m.
Kinetic energies of three fragments are
And 
Total kinetic energy released during explosion
