    Tell me why you think you can assume that each piece gets the same amount of energy?

    Im not going to lie. I guessed. Wish to give me a better idea of how to tackle this?

    What is the definition of an elastic collision?

    Ah...

    so what I have done is conserves ALL of the kinetic energy!! This lets me set up some simultaneous equestions with the momentum and all the kinetic energy conserved.

    This gives me: v1 = 254.4m/s

    and v2 =46.2 m/s.

    does this seem correct (i havnt got the answer!) i can post all the workings if that helps.
