How Does a Ball's Horizontal Motion Affect its Fall ...

The ball's vertical motion is that of a falling object. The ball rises quickly at first, then more and more slowly. It's momentarily neither rising nor descending, and then it descends more and more quickly as it approaches the basket. The ball's horizontal motion, the motion along the downfield coordinate direction, is that of a coasting object.
