A 5.80 kg ball is dropped from a height of 14.5 m above one end of a uniform bar that pivots at its center. The bar has mass 9.00 kg and is 6.40 m in length. At the other end of the bar sits another 5.30 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?
