A 4.80 kilogram ball is dropped from a height of 10.0 meter above one end of a uniform bar that pivots at its center. The bar has mass 6.50 kilogram and is 7.20 meter in length. At the other end of the bar sits another 5.60 kilogram ball, unattached to the bar. The dropped ball sticks to the bar after the collision.
Evaluate how high will the other ball go after the collision?
