A gentlemen on another site, not related to physics stated the following:
[moderator removed personal information of third: indeed something that is inappropriate without consent]
Bullet speed is relative. A .22 long rifle compared to the .22-250 is a great example. The SR-71 Blackbird aircraft was surreptitiously as the YF-12A fighter airplane until they realized that, at speed, the YF-12A was flying faster than the machine gun bullets it fired and that they would actually explode inside the gun magazine if fired.
This particular rocket, accelerated after it passes the hold of Earth's gravity can attain and maintain a speed of 47,000 miles per hour, yet light travels at a speed of 186,000 miles PER SECOND. Doesn't seem very fast when compared to the grand scheme of things, does it.
My theory, using my very limited knowledge of physics is: If an aircraft is flying at Mach 3, the weapons in the aircraft, are also moving at Mach 3 until they are fired. When they are fired, the speed of the bullets or projectiles would be Mach 3 plus the speed of the bullet upon firing.
Thanks in advance, Bill
