Questions 1. From the graph, what angle gives the maximum range for each case? ............................................................................................................................................... ............................................................................................................................................... ............................................................................................................................................... ............................................................................................................................................... 2. Is the angle for the maximum range greater or less for shooting from an initial height? ............................................................................................................................................... ............................................................................................................................................... ............................................................................................................................................... ............................................................................................................................................... 3. Is the maximum range further when the ball is shot from an initial height or on the level surface?
