you plan to drop a ball off a cliff.the ball will fall straight down for some distance,then bounce off a hard angled plate .when the ball bounces,the plate will redirect it from falling vertically to shooting perfectly horizontally without changing the balls speed then the ball will follow a parabola to ground..the plate can move up and down,meaning you can choose d.
