I am making a game where a 4.90 -kg ball is dropped from a height of 12.5 m above one end of a uniform bar that pivots at its center. The bar has mass 7.50 kg and is 9.00 m in length. At the other end of the bar sits another 4.40 -kg ball, unattached to the bar. The dropped ball sticks to the bar after the collision. How high will the other ball go after the collision?

So adding the words "I am making a game where" and changing the thread's title makes it not your homework anymore? Or did you not quite understand jpetrie?

It'll go about 15 and a half meters high.


I tried using conservation of momentum and got that answer too, but amazingly that is not correct. I put it into my game, and it does not work.
