Ok so far I have been thinking that an explosion is nothing else than a inelastic collision. So energy is lost and momentum is conserved therefore [tex] P_i = P_f [/tex], The problem asks for how much kinetic energy did each piece aquire in the explosion, I also know that there was 7800 J released.(adsbygoogle = window.adsbygoogle || []).push({});

In order to make calculations easier I come up with:

[tex] m_a=1kg [/tex]

[tex] m_b=1.5kg [/tex]

[tex] E=7800J [/tex]

I can set up the problem but I can't see further steps I need a bit of explanation please.
