(1)What is the final velocity of the 44 kg ball?

(2)The final velocity of the 86Kg ball?

Answer in units of m/s

- Physics -
**bobpursley**, Wednesday, August 10, 2011 at 12:13amyou have to use both conservation of momentum and energy.

Start with conservation of momentum, solve for one of the ball's velocity in terms of all the other variables, then substitute that into the conservation of energy.

The algebra is substantial, so be prepared.
