[Everyone will be throwing an apple out the window today to test this theory] Be careful, my sister got a $200 ticket for throwing an apple core out the window on a highway once. That's the police hard at work protecting the people. ________________________________ From: Daniel Rodriguez [mailto:[email protected]] Sent: Tuesday, October 13, 2009 5:12 PM To: NT System Admin Issues Subject: Re: test...sorry.. Ok. If you are moving 60 mph in a car that means everything in the car is moving at them same speed. Even if the apple is sitting in the passenger seat it appears that it is not moving. That is because the driver, you, are making your judgement based upon your oberservations. Take that same apple and throw it out the driver side window. It does not move backward. It moves forward! You, the driver, will see the apple move away from the car, initially, but then the apple looses momentum and then appears to move backward. But since your speed is constant, assuming that you do not slow down, you actually outpace the apple. If you were to slow down at the same rate the apple looses momentum then the apple will still be to your side being neither in front of or behind you.

Direction relative to what? Relative to the driver, who is traveling with the car, the apple will appear to go backwards, because it will immediately hit air resistance. (I'm assuming an atmosphere and constant velocity of the car.) Relative to the ground, the apple will appear to be traveling forward with the car, and then gradually slow to a stop. In both cases, the apple also travels away from the car ("throw"), and also falls down (assuming gravity). Baring glancing blows altering the trajectory, all motion vectors should be independent of each other. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/ <blockedhttp://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> > ~ Classification: UNCLASSIFIED Caveats: NONE ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
