A 4.60-kg ball is dropped from a height of 10.0m above one end of a uniform bar that pivots at its center. The bar has mass 8.00kg and is 5.60m in length. At the other end of the bar sits another 6.00-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?
