... It's really not too much to ask that you differentiate puzzlers from legitimate requests for help. Although it was not in my original query, I *did* explain exactly where the question arose and my purpose in asking it. You must have missed my post of September 7 @ 6:35 PM in reply to "abripl". I quote: "I brought this subject up because I was reading an article in the May 1942 issue of "Flying and Popular Aviation". It was titled "Speedy" and tells the story of a quiet young fellow named Andy McDonough who dove a new Army fighter to 620 mph a "few weeks ago". He'd like to try for 700." The airplane was a new P-39 Airacobra. "After his test, McDonough said he thought of that now-famous problem: 'I wondered what would have happened if I could have fired a pistol back over the tail. At that speed would the bullet have rolled out of the barrel and then fallen back?'". Well, perhaps that was a famous problem in the spring of 1942. I don't know, having entered this vale of tears late in 1941. But I thought it would be fun to toss it up here among all these reasonable, logical, polite folks. " I have already stated that I regret not stating the problem more clearly and I feel that it has been obvious from the beginning that I wasn't really asking for help in attempting to shoot down a Hun. My viewpoint. Now, shall we put this dog to sleep? We both have more serious things to worry about, I'm sure. Rich S. |

... Yep - Sorry if I seemed a bit grumpy - It's other things, not you - I actually like physics puzzlers. Know what you mean. They said my back surgery would last ten years. It's been nine and the Vicodin count is rising rapidly. I am also sorry for yelling. Rich S. |

Oh come on you guys.... don't get serious now... that would ruin your

If I gave offense, it was unintentional, and I apologize. (I can hear the Usenet gasps - an apology! - coming through my network connection :-) From my point of view, someone asked for help, I spent time trying to give it, then I found out that it was a trick question, somewhat poorly expressed at that.

I've been out of flying twice this year with a back problem. While I was out, a developer signed a contract to buy our airport (N82) and the current airport manager is destined to be his partner. The town offered to buy the airport for more money than the developer, but the executrix of the estate and heir to the airport property sold it to the developer instead. (Two of the 4 heirs fought the executrix, as they love the airport, but one recently died of appendicitis, and the other is being evicted from her family home on the airport property.) The town doesn't want to lose the airport. The pilots were told if they spoke at the town meeting against the developer they'd be kicked off the airport. There are laws against coersion I'd have my lawyer suit for enough for you to take over the airport for payment! ;-) John I put developers in the same catagory as doctors (especially FAA!) and lawyers. |

You've made an irrelevant assumption here.
The answer is "It's all a matter of relativity" With the correct lead, it does not matter what speed relative to the ground the bullet is travelling, relative to the two aircraft is what is important. remember the bullet is spinning so also maintains some gyroscopic stability. All bullets fall to earth at 9.8 m/s^2 regardless of their path over the surface of the earth. With the correct lead the bullet and the ME-109 colide, at which point the tragectory of the bullet is drasticaly altered such that it, and teh ME-109 all fall/fly to earth as one mass. If the case is simplified such that the bullet is simply fired backwards but at nothing, then it will accelarate to earth, only with a 0 lateral velocity relative to the ground. Rgds, "Rich S." wrote in message ... There is a (magic) B-17 flying along at 560 mph. The tail gunner is out of .50 caliber ammo. He sees a Messerschmitt ME-109 crossing behind the B-17, 50 yards away. He pulls out his trusty .45 Colt auto (muzzle velocity 820 fps) and fires at the Hun when the ME-109 is directly behind the B-17. He leads the Messerschmitt by exactly enough to hit the pilot (if he were firing from a fixed position). Does the bullet exit the muzzle and fall directly to earth? Rich "Scratching my head" S. |

Quick question: what does a plane have that a bullet lacks?
Answer: an engine to maintain its speed. Bullets start slowing down the moment they leave the muzzle (alright, just slightly *after* they leave the muzzle), while the aircraft that fired them can maintain its speed. But in this case there is no air friction to "slow" the bullet. It leaves the gun into still air, and so if the bomber is accelerated a bit by the gun's recoil, its muzzle velocity is a bit less than the airplane's velocity and so will move "forward" a little as it falls.
