For guns with a similar barrel length, the bullet velocity for a given
cartridge will be fairly close.
Most usual 9mm loads, with bullets in the 115 to 125 grain range, are
supersonic when fired from most handguns and have a velocity in the
range of 1100 to 1300 feet per second.
The .45 auto fires the .45 ACP cartridge and the most common bullet
weight is 230 grains which is propelled at between 800 and 900 feet
per second.
Stopping power is dependent on many more things than just bullet
weight and speed although those are very important because they
combine to give the bullet kinetic energy and momentum which are
critical to stopping ability. Also important is the way the bullet
expands if hollow point bullets are used.
If we don't use hollow points, energy and momentum become very
important but the size of the bullet also becomes important.
According to the tables from ProLoad Ammunition at
http://www.proload.dmi.net/specs.htm, the average 9mm and .45 have
very similar energy ratings. The .45 makes a bigger than the 9mm and
arguably is a better stopper but others will argue about hydrostatic
shock damage by a supersonic bullet.
When it comes right down to it, I don't want to be shot by either. :-)

I'm assuming that you are talking the 9mm and the .45ACP. Well, the 9mm
is faster than the .45, however they are of different bullet weights.
.45 is obviously heavier thus despite the decrease in velocity,
generates more energy.
Rough estimate speed without really testing it on a Chronograph to test
the true load:
9mm in 115fmj is about 1250-1300 fps
.45 in 230fmj is about 860-900 fps
assuming both out of similar length barrels like around 5 inches.
Speed does depend on barrel length...ideally the maximum velocity is
reached when all the powder is burned inside the alotted barrel length
and builds enough pressure before the bullet creates "drag" due to
excessive barrel length.
Most probably it didn't answer all your questions, but hope this helps.

# I was wondering how fast the average 9mm bullet goes,

A 115-grain 9 X 19mm round's nominal velocity is 1250 fps.
A 230-grain .45 ACP round's nominal velocity is 850 fps.
# I hear that the 9mm is considerably faster, which can

Get a book on external ballistics... avoid like the plague any
texts on this subject by Marshall, Sanow, Fackler, Jason or
Roberts.

Is this flame bait?

"Stopping power" is a myth in the realm of handguns. Proper placement of the
round in the attacker is the ONLY reliable way to stop an attacker with a
handgun round, be it a 9mm or .45. If you don't hit a vital area, your chances
of stopping the attack are spotty at best, regardless of the handgun you use.
Read up on this topic, about actual shootings, and you'll believe.
If you want to split hairs, the .45 does make a bigger hole, and that's
better. But that hole isn't EVER big enough to make up for poor shot
placement. If you hit vitals with a good 9mm hollowpoint, you'll be well on
your way to winning the gunfight.
Take your pick from any gun in anything from 9mm on up - your handgun should
be the one that #1 is reliable #2 you can shoot most accurately under stress
(out to 15 yards or so) #3 you can control under recoil to quickly follow up
shots

Got some factual data to back up your unrecommendation of Fackler ?
Seeing as you obviously don't believe anything anybody writes, is there
anyone who has any credibility in your opinion ?
You say to get a book on ballistics but by whom ?
I laughed like hell when you grouped all those folks together - I don't
there is any other way you could have insulted all of them
simultaneously.

A wholehearted second to the above statement. All of the .45 v. 9mm
argument is just Chevy v. Ford arguments. Either one gets the job
done, if you hold up your end of the bargain.

try telling that story to any soldier in the army during the Philippine
police action when they were buying out of their own money, colt single
action army pistols in 45cal because their 38specials (which hit harder than
9mm) wouldn't stop the Morays.

Actually, the Army issue at the time was .38 Long Colt, which was loaded with a
150 grain bullet at 770 fps and a muzzle energy of 195 foot pounds. Not as good
as most 9mm loads.
The .38 Special was developed because of the problems with the Long Colt
cartridge.
# wouldn't stop the Morays.
Why were they shooting eels, anyway?

I would, if I could find one who is still alive. But, if I did, he'd probably
tell me that the issue revolvers fired the .38 Colt Long, not the .38 S&W
Special.
The .38 Long Colt developed considerably less energy than the 38 S&W, which, in
its military loading, develops quite considerably less energy than the military
loading in the 9mm Para..
The Army re-issued SAAs, so the troops didn't have to buy their own. As it
turns out, the hopped up Moros weren't reliably stopped by the .30 Army out of
a Krag, so the .45 Colt probably wasn't that much of a problem solver.

Actually, from what I've read, even the .45 wasn't an absolute guarantee to
shooting those doped up, hard charging tribesmen. But, the size of the bullet
did boost morale.
It seems like the ONLY weapon that was pretty well a certainty during the
insurrection was a shotgun armed with 00 buck. Just like white hunters used
to use on tigers or lions for "close-in" work.

Well, no. But I thought they were called the Moros...
