An internal explosion breaks an object, initially at rest, into two pieces, one of which has...

An internal explosion breaks an object, initially at rest, into two pieces, one of which has 2.0 times the mass of the other. If 7800 J is released in the explosion, all of which goes into the kinetic energy of the two pieces, how much kinetic energy does each piece acquire?

I'm not really sure how to go about answering this one. If anyone could help me out that would be great! Thank you so much in advance
