A diver leaves a 3 m board on a trajectory that takes her 2.5 m above the board and then into the water 2.8 m horizontally from the end of the board.
Find the horizontal distance of the diver from the end of the board when she is at her maximum height.
If calculus is necessary don't hesitate. If you found that humorous, good.
