what (and where)is the extremity of speed?

According to Einstein, no object can go faster than the speed of light, approx.186,000 miles a second.

The fastest recorded instantaneous velocity achieved by a human was supposedly by Donovan Bailey, who set the World Record in the 100 m (9.84 s). He was clocked at 12.1 m/s, although this figure is perhaps a bit rough (recorded by a radar gun). Accurate data was taken at the 1997 World Championships in Athens, where the top speeds of both Maurice Greene and Bailey were recorded at 11.87 m/s (although neither set records in the race -- Greene ran 9.86 s to Bailey's 9.91 s). Bailey was also clocked at 11.91 m/s in the 4 x 100 m relay final at the same championship. They include wind factor in these calculations.\n\nOtherwise : Asafa Powell 9.77s (1.6 positive wind) 14/06/05 then again in 11/06/06 & 18/08/06.\n\nI personaly prefer this one: Paul Tergat from Kenya running a marathon in 2:04:55 on the 28/09/2003 in Berlin....now, that's fast !!\n\nIf you're interested in other distances, check out the below link.

speed limit for ambluance? ohoh..I should learn something here too.

faster than I can swim

It doesn't translate.  Some people are very quick...get to full speed in a hurry.  Others take more time, but reach faster speeds.  It is much like the Quarter Horse vs Thorobred.  Have I confused you enough?  I could go on....

UMMM NO.  What kind of question is that????  If someone is moving that fast on you, you better be careful.

Speed and direction, if thats what you're asking

The horizontal speed will be maximum at release.  However, gravity will add vertical (downward) speed.  The speed in the direction of motion may actually increase depending on the amount of air friction, and the mass of the ball.  The mass will not affect downward acceleration, but will affect the slowing effect of air friction.  This is actually an interesting question and you have intriqued me to try and solve it: is there a maximum velocity in the direction of motion?\n\nIt can get quite complicated since the vector sum of vertical and horizontal velocities is continuously changing as the ball accelerates downward and the trajector points down.

the number that can be reachable tha most?

Minimum speed for what?\nIf you want to leave earth orbit then you need to be over the earth escape velocity.

the velocity of the ambient

Gravity won't let you. You have to go into orbit first, and 1 mph will not do that. You have reach escape velocity to escape earth's gravity, which is 11.2 km/s.

Hi: Something less than 95 mph as force has been \n exerted in a direction somewhat against the direction of the pitch.  Ken

It depends on your frame of reference.  Relative to the Earth, the fastest speed man is capable of is probably 10km/s, that's 1/30000 the speed of light.
