This looks like a question I answered earlier today. Why are you posting it again?

anyone else know how to go about solving this complicated problem?
Your friend has climbed a tree to a height of 6.00 m. You throw a ball vertically up to her and it is traveling at 5.00 m/s when it reaches her. What was the speed of the ball when it left your hand if you released it at a height of 1.10 m?
