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?

What is the definition of an elastic collision?

Ah...

so what I have done is conserves ALL of the kinetic energy! This let's 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.

Go ahead and post the work.
