   How fast can a human being run?
   
   Many types of animals can run very fast. Many birds can fly too fast. How about us? the human beings?

   A one Usian Bolt from Jamaica held in, I believe 1996 or 1999, perhaps still does, the world record for the 100 meters at 9.58 secs.
   I've heard it said that man is the fastest accelerating animal.

      Is it possible? "man is the fastest accelerating animal?"

      I don't know the veracity of that statement, only that I have heard that man is the fastest accelerating animal. Or should that be mammal?

      I'm quite sure it isn't man.  According to the following link, it's either the cheetah or greyhound:

      Sorry wandreth, that site doesn't indicate that, there is part of in that refers to the speed of theses animals, but I can't find reference to acceleration.

      We have Bolt = 0 - 44.73kph over 60m, greyhound = 0 - 70 kph over 30m and cheetah = 0 - 96.54kph in 3sec.  Calculating the acceleration, we have Bolt = 1.287 m/sec2, greyhound = 6.301 m/sec2 and cheetah = 8.939 m/sec2.  Cheetah wins.

   From MickS' answer that's 10.43841meters per second average. That's 37.5783kph average. Half the speed of a cheetah. But that's on the outer extremes. I think most people can do around 25-30kph.

      I think it is not possible for the common man to maintain 25/30 km/h speed for more than 15 to 20 seconds. What do you think?

      yes, because that's sprinting speeds.

      The question didn't enquire of stamina, only how fast.

   As MickS said, Usian Bolt ran the 100m in 9.58 sec, which translates to a speed of 37.58 kph.  But during the 60m - 80m stretch, Bolt averaged a speed of 27.8 mph or 44.73 kph, which is perhaps the fastest a human can run at the present time.

      How fast will you run if you saw a 100 pound size diamond is on the road to pick up and own if you beat others in race?

   It all depends on what makes the human run. I feel he will run the fastest if he was being chased by a lion.

      He will run much more faster if you promised him to give $1 million if he can defeat a race horse by running only.

   I know running a 4 second flat forty yards is pretty fast? That's 10 yards per second. Hopefully someone is better at math than me?
