 `Can 2 basketballs pass thru a basketball hoop at the same time?` Request for Question Clarification by scriptor-ga on 06 Feb 2004 12:39 PST ```Just in case this is a trick question: Do the baskeballs have to be filled with air? Regards, Scriptor```
 ```Hi yar, Let's start with Scriptor's clarification request. If the two balls are deflated, then the answer to your question is yes. Now, if we're talking about two fully inflated, one by one, side by each, official basketballs, we need to consider the circumstances, starting with a definition of 'diameter.' "The length of a straight line through the center of an object from side to side; width; thickness; as, the diameter of a tree or rock." Dictionary.com/diameter http://dictionary.reference.com/search?q=diameter&r=67 `````````````````````````````` Now, we need to know the official diameter of a basketball hoop. "Today's basket is an 18-inch-diameter (46 cm) metal rim, with a 15- or 18-inch-long (38 or 46 cm), open-ended nylon net extending below it." What is the diameter of a regulation basketball hoop? : Basketball http://www.answerbag.com/q_view.php/1504 `````````````````````````````` So we know how big the hole is, but what about the object(s) we want to pass through it? "The official basketball of both men's N.B.A. and N.C.A.A. leagues is a size 7. This ball has a diameter of apporimately [sic] 9 inches, and a total circumference close to 30 inches." The world of basketball is full of geometry http://keiththebeef.tripod.com/bball3.htm `````````````````````````````` We've got the facts, but the answer can't be derived from them so easily. Here's my take on it. It is 'possible,' but not probable. One could attach the said balls together precisely and, by hands-on pressure, force the balls through the hoop. One could attach the said balls together precisely and, by means of a free-throw, connect with hoop, but without added pressure, no matter how precise the throw, the balls would not pass though. Perhaps Michael Jordan could make one of his amazing slam-dunks, and if he's lucky, force the balls through. Another scenario is that the balls are attached and pass through the hoop vertically, as opposed to horizontally. In that case, there would be no reason the two balls couldn't pass through easily, at least when dropped through. To be shot through, it would depend on the skill of the shooter, but it's possible. I think the answer to your question, in theory, is yes. In practice, barring a fluke, your answer is no.

As a matter of fact, the ONLY way the balls could go through the hoop is if someone did exert downward pressure. It wouldn't be possible if we were talking about rigid bowling balls or golf balls, whose shape can't be altered. A basketball has a flexible exterior and is air-filled. Thus, although its volume remains constant, its shape can be altered under pressure. If you take the time to watch the process in your mind's eye, you'll see that the difficulties presented are virtually insurmountable. Five yards to the left and eight feet out from the basket is Meadowlark Lemon. Five yards to the right and eight feet out from the basket is Michael Jordan. At exactly 7:43 pm, each player shoots, with equal force, on the basket. Now, what's going to happen? The two balls meet over the basket and bounce of each other. Neither, much less both, ball passes through the basket. The two balls were shot with just enough force that they drop to the basket without touching, so no bouncing. They don't touch, and assuming they are exactly equal in height, there is no way 18+ inches can pass simultaneously through an 18 inch hole. I'm not sure how I can better explain the conundrum, but I'm willing to try. Regards, revbrenda```
