The speed on sound is about 761.2 miles per hour or 4,0191,136 feet per hour.
Or 66,985.6 feet per minute
Or 1,1116.42666 feet per second.
If a person was to swing a Kata in a complete circle having a diameter of 9 feet at the tip of the blade, he would have to be able to complete that circle in less than one 39.5 of a second.

The short answer is that using a standard katana, it is not possible. However, if the length of the katana increases, and the holder swings the katana at a uniform rate as a shorter one, then, there is a theoretical length at which the tip of the katana would break the sound barrier.
For comparison, Maurice Allen is recorded by Guinness as having the fastest golf swing at 211 miles per hour. He did it with a 3-wood - comparatively shorter than a driver, a testament to the fact that technique trumps everything, and his technique was optimized for a 3-wood. A 3-wood, by the way, is still longer than an average katana, suggesting that anyone who swings it would have to do it closer to 4 times faster than Mr Allen's golf swing.
Assuming the speed of sound is 660 mph, that comes out to 968 feet per second.
Assuming the tip of the katana in the spinning swordsman's hand describes a circle 6 feet across, then the tip travels 37.68 feet per turn.
968 / 37.68 = 25.69 revolutions per second.
My guess is that even the strongest swordsman, with years of training and experience, won't be able to turn that fast. And if he got close to it, centrifugal force would pull the sword from his hands and fling it off in some random direction. Even Olympic figure skaters are only turning at the very most 4-5 revolutions per second, and they can do that only by drawing their arms in close to their body, and on a nearly friction free surface. Extending their arms slows them down radically.
Yes, but only if you attached the katana to the nose of a fighter jet plane that's flying past mach 1.
First off, it's not the finest sword ever made. It's the sword with the most hype behind it. Vikings made very impressive swords long before Japan. Secondly, it depends on how it got in motion. If I swing it, not knowing how to swing, no it won't. If I drop it out of an airplane at 20,000 ft, yes it would.
Finest sword ever made? Lol.
And in short, no. No it cannot.
Nope, but the "crack" one hears from a whip snapping is its loop breaking the sound barrier.

No no never Mwahaha...
if someone does do it please upload on youtube so we can al view it
So what I'm asking is: can a Katana (Japanese Sword) which is the finest sword ever made and maybe ever will be, break the sound barrier with a slash?
A truly made pure Katana created from the purest iron in the world extremely light yet incredibly strong with a trained Iaido master with years of training and experience.
Can he pull his sword into a slash so fast that the Katana actually breaks the sound barrier?
if not what's your estimated top speed for the Katana? (consider the Iaido master 1,5 times as strong as the average human and his hand speed is at least twice as fast).
