Can you break sound barrier falling from sky?

Author: admin Category: 5

Supposedly the guy that jumped from a balloon from over a 100 thousand feet broke the sound barrier falling at about 1100 feet per second about 1960; how come sky divers do not come close to that rate of falling?
It was Capt Joseph Kittenger that jumped from a balloon at 102,800 feet in 1960. He [...]

Suppose you had a classic world war two aircraft. It somehow managed to break the sound barrier regardless of?

Author: admin Category: 5

the drag it’s geometry created. What would happen to it? Would the aircraft survive at the speed of sound or would it’s wings shatter, or something around those lines.
There were many claims during and after WWII about aircraft breaking the sound barrier. The P-47 Thunderbolt, Me-262 twin-jet (first operational jet fighter), and Me-163 Komet [...]

Vapour field and breaking the sound barrier?

Author: admin Category: 5

In layperson’s terms, what causes the physical manifestation of the vapour bubble around a plane that breaks the sound barrier?
The shock wave is a sudden build up of pressure in the air. When this pressure passes by, the compressed air suddenly expands and cools. If there is enough water vapor in the air [...]

Author: admin Category: 5

I see many are saying the bull whip, but wasn’t it actually the slingshot? A slingshot similar to those used in biblical times breaks the sound barrier when used.

I have a new home, the master bedroom is above the kitchen and the genius builder didn’t insulate between the floors. It doesn’t matter how softly or hard someone walks across the floor, it wakes me up b/c of [...]

What would happen if you broke the "sound barrier" in water?

Author: admin Category: 5

I know that the "sound barrier" would be 4.3 times faster in water but its just a theory question.
Very similar phenomena to what happens when you break the "sound barrier" in air.
It is just MUCH more difficult to do so in water, because water’s speed of sound is much greater, and water fluid drag effects [...]

I just moved into a condo and want to insulate my walls with some kind of sound barrier, without having to remove any drywall. I’ve heard of insulation being blown into walls, was wondering if there’s something similar that assists with sound?
There are various materials that can be injected into the walls , green [...]
