How much speed is needed to break the sound barrier?

At first glance, it seems that the faster you go, the faster sound travels. This is partially true. However, the relationship between speed and the speed of sound is not that simple. Speed is a product of the square root of the density of an object divided by the speed of sound. The faster something moves, the thinner it becomes. But the sound wave will also travel faster through a thin object. To break sound barrier, you would need to go the speed of sound through a very thin

How fast is it to break the sound barrier?

The sound barrier is about 1,236 kilometers per hour (784 mph . That is faster than the fastest recorded run on earth at 6.68 miles per hour. The sound barrier is broken by supersonic jets and missiles.

How much speed is needed to exceed the sound barrier?

The speed needed to exceed the sound barrier is about 1.2 times faster than the speed of sound. This is known as the critical mach number. The critical mach number is dependent on a number of variables, including the size and shape of the object traveling through the air.

How much speed is needed to break the sound barrier without pilot?

It's possible to break the sound barrier without a pilot on board, although it's much more challenging. The first successful tests were made in 2006, when a Boeing 747 was flown using only its engines. The jet was flown at about 1.7 miles above the ground at a speed of 1.7 times the speed of sound, and it created a sonic boom. The noise level produced by the aircraft was lower than that of a traditional sonic boom sound, possibly because the jet was moving so slowly

How much speed is needed to get break the sound barrier?

We’ve all heard it: a sonic boom is created when something moving at the speed of sound travels over a fixed location. It’s no exaggeration: sound does travel at a speed of about 340 miles per hour, which would allow a person to travel the length of a football field in one-thousandth of a second. When a commercial airliner flies at cruising speed (about 575 mph), those engines create a sonic boom over the ground below. A supersonic airliner
