Musket shot? or cannon shot.

The whip. The loud snap you hear when cracking a whip is the shockwave from tip of the whip going supersonic.

Wikipedia is your friend, scroll down to "Bullwhip" (http://en.wikipedia.org/wiki/Sonic_boom)

Yep, thats right. Thats only the tip though, not the entire object.

Semantics I guess.

I was thinking of a musket shot too but the whip came before that huh? http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

If the question was..."what was the first man made object capable of breaking the speed of sound?", I would have to agree with you...but the question is, "Anyone know what the first man made supersonic object was?"...so I will have to stick with my original answer. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Does that mean it's not moving at supersonic speed? http://forums.ubi.com/images/smilies/35.gif

Since the mean orbital speed of the Earth is a tad over 29km/s - it would therefore be the first object man fashioned. http://forums.ubi.com/images/smilies/winky.gif

Whip.....

But certainly as an object flying
faster than sound it is a muzzle loaded
musket/rifle ball.
With black powder in modern heavy small calibre
muzzle loaded rifle velocities nearing 2,000 fps
can be attained.

I would guess a top quality 18'th century (1700's)
small calibre rifle ball could safely see 1,400 fps
or about mach 1.2.

Cannon were always a low velocity affair Until
the advent of nitrocelluous propellants (Smokless Powder) and rifled cannon roughly in the 1880's.

I always thought that the cracking sound which came from a whip occurred because the tip of the whip struck a part of the whip located lower down at high speed.

When I used to throw punches at karate practice many years ago, I could get a muffled cracking sound to occur.

The last time I popped a wet towel at someone, there occurred a cracking sound.

I thought that in all these cases, the sound occurred because of one object striking another at high speed (like the sleeves of my karate outfit slapping against each other, or the towel striking flesh).

I reasoned that a similar thing must be happening in the case of a whip. How's that for an explanation ?

I felt that "a supersonic object" (as the question is phrased) insinuates the "whole" item, not just a part of the object...so I answered "a musket ball or cannon ball". In the end, the issue here will be a matter of semantics (as you point out)...


Science quizzes, puzzles and game's (like a good joke) must be "set-up" properly for them to work "right"... http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Though only seen in cave drawings the first known sonic boom was an angry cave-woman making her cave-man take out the garbage....

Hence the name, "Thunder Clubs".....

2) An Arrow (Bow and Arrow).

No, even the fastest arrows won't exceed speeds of 100m/s.

M 1 is about 330m/s at standard conditions.

Not really... a dog whistle will produce a sound of ultrasonic frequency, but this high-frequency sound wave will still travel at the same speed as ordinary sound http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

With modern man made components, and computer designed parts, the fastest arrows are still half the speed of sound.
muskets, be sure- 1200fps assuming they tried at sea level, eh?

A husband, who had been informed by his wife that she was "in the mood."

A vacuum does not preclude an object moving faster than sound, although sound itself will not progagate in a vacuum.

My point was simlpy that when we envisage relative velocity we always use the illusion of a stationary object on earth as the reference, I was just stating that our reference point is itself not stationary.
