Approximately 720 miles per hour
The speed of sound has been officially broken multiple times. The most notable instances include Chuck Yeager breaking the sound barrier in 1947 and the ThrustSSC breaking the sound barrier on land in 1997. Additionally, different aircraft and fictional vehicles have broken the speed of sound in various testing scenarios.
I don't believe anyone has broken the sound barrier on land yet.
The sound barrier was first broken on October 14th, 1947.
its simple the sound barrier is broken :D
the speed of sound at sea level :)
A sonic boom is created, basically a hole in the atmosphere
Yes, depending on which aircraft you have but there is no indication that you have broken the sound barrier unfortunately.
To the best of my knowledge, the sound barrier has never been broken by an automobile.
No, helicopter blades do not break the sound barrier. The tips of the blades can approach the speed of sound, but the entire blade does not exceed the speed of sound.
With a whip...
Exceeding the sound barrier refers to speed of travel, not loudness of sound. A speaker cannot "exceed the sound barrier".
