How fast can a cheetah run? I've heard 60, 70 & 80 mph but what's this based on? Radar guns or guesses?

The Cheetah (derived from Sanskrit word Chitraka meaning "Speckled") (Acinonyx jubatus) is an atypical member of the cat family (Felidae) that hunts by speed rather than by stealth or pack tactics. It is the fastest of all terrestrial animals and can reach speeds of up to 100 km/h (62 mph) in short bursts

Checked with a friend of mine he advises me you have LASER, some hand held portables  radar ka guns, and some units have Vascar a non radio in car computer based on officer observation.\n\nThis is connected to the vehicles speedometer through a sensor that feed both the computer and the radar and corrects the vehicle speed indicated for patrol car speed.\n\nAPS

It's 220mph, near enough, so you're looking at perhaps a bullet, or a jet. It might be worth dropping it to 49 m/s (110mph) or even 24.5 m/s (55mph) to bring it within the range of a sports car or ordinary motor.

Tigers can run about 35 miles per hour (56 kph) — roughly as fast as bears and lions. They reach such speeds only over short distances (about 10 yards, 10 m) during the attack.

Assuming he doesn't get tired and can run at that pace:\n8.3 m/s x 60 secs/min x 60 min/hr x 10 hrs = 298,800 m\nObviously this is too fast. I believe you meant that the bear runs 8.3 m/hr. \nThen it would be:\n8.3 m/hr x 10 hrs = 83 m\nWhich is a little more realistic.

A cheetah has a few body adaptations that helps it achieve such great speed.  A cheetah has long legs, a slender body, and a flexible back bone.And the claws of a cheetah do not retract like those of other cats.The cheetahs claws give it more traction thus enabling it to run much faster.

This is easy: d = v*t + a*t^2\n\nBut you had the cheetah at a standing start (v = 0 m/sec), so this simplifies to:  d = a*t^2\n\nRearrange the equation to get : t^2 = d/a, so t = square root of (d/a)\n\nd = 30 meters\na = 7.8 m/sec^2\n\nt = (d/a)^½ = (30/7.8)^½  = 3.85^½ = 1.96 seconds

Cheetahs are roughly the size of a very large dog (excluding Great Danes, not quite THAT big), but with much sharper claws and teeth. So if you annoy one, by threatening its cubs for example, consider yourself supper.\nBut they generally avoid people if they can.

It takes about 1/4 mile for a really fast horse to hit maximum speed...\nSome pretty incredible speeds have been attributed to gaited horses, crediting them with hitting 40 and even 50 miles per hour (m.p.h.), Let's consider some verifiable records.\nMarch 5, 1989. Racing on a dirt track at Santa Anita racetrack in California, a Thoroughbred named Ruhlmann, age four, carrying a jockey and saddle weight of 118 pounds, ran one mile in one minute, 33.4 seconds (1:33.4 minutes)That represents an average speed, from a standing start, of 38.54 m.p.h.\nMarch 1, 1997. Racing on a faster grass track at Santa Anita, a Thoroughbred named Atticus, age five, carrying 117 pounds, ran one mile in 1:31.8 minutes, averaging an even faster speed of 39.21 m.p.h...Sprinting Speeds\n\nLet's now consider the American Quarter Horse, specifically the sprinting race horse. After generations of being bred to sprint, a good one can chew up 350 yards of track in about 17.72 seconds. [Reference 2] That's a sprinting speed of 40.40 m.p.h. Some have been clocked at 45 m.p.h. Now that's a "burst of speed" from an equine athlete bred to do one thing really well... sprint!....\nSpeed in Trot and Pace\nLet's move on to gaits that have similar (though slower than a gallop) locomotion to our own gaited horses. Keep in mind that a trotter (two-beat, diagonal gait) and a pacer (two-beat, lateral gait) have only two beats to concentrate on. A gaited horse (four distinct hoof beats somewhere between a dead trot and a dead pace) has twice as much to regulate. That's why it is harder for a gaited horse to accurately maintain the gaits required by their breed standard.\n\nLet's look at an interesting trotting fact. The Standardbred harness racing stallion, Pineship, at four years old, trotting an average speed of 32.43 m.p.h., set a new world record of 1:51.00. His time reads T4T 1:51:00M.\n\nHere is another juicy little tidbit, this time from a harness pacer. Cambest, a five-year-old Standardbred stallion blistered the track at an average speed of 33.89 m.p.h., setting a new world pace record. His time reads P5T1:46.1/5M.

Dihatsu .2 liter weedeater XP90, yea she runs on a 20:1 gas/oil ratio, got her up to 26 mph going down hill, shes pretty sweet, Id take u off the line, but I think you have me top end, get a life\n\n--truth is son, I run a new gsxr750, it does 188mph 600 from redline, but any retard can go in a straight line and mash the pedal, but, where technique really counts is in the mountains and on the twists, in which case son, you would be eaten alive, and guess what, i spent 60000 less than you...now whos the tard? hahaha

Okay, I've thought about this and it's not possible to determine the rate of acceleration from the given criteria.  It is an "average" of 60 miles per second, BUT how many miles in the first second compared to the number of miles in the final, fifth second?  If that is known, you can project MPH from seconds 6 to 10 or the additional 1/4 mile.  How do you calculate the rate of acceleration in your theory?  How fast is the vehicle traveling at each point of the 1/4 mile distance?

Cheetah is the fastest animal on LAND.\n\nOverall, 'peregrine falcon' (a bird) is the fastest animal. It reaches speeds upto 200 mph!! (Cheetah only manages abt 70 mph)

depends on which one is running faster.   pantherfan

Left or right? <g>\n\n15 to 80 times per second (depending on the size of the bird).\n\nMultiply that by 60, OK?\n\n"Q: How fast do hummingbirds flap their wings? \n A: For small hummers like Ruby-throated, about 55 times per second. Normal flight speed is about 25 MPH." \n\nSee link ...

I have no idea but probably like 70 maybe 85mph.

As Ben Kenobi told Luke, "You must learn the Force."\n\nYou must learn the term Frame of Reference.\n\nIf you are on the jet doing 3000fps.  How fast are YOU moving with respect to your frame of reference.  Answer  ZERO!  Things are coming at your frame of reference at 3000fps.\n\nSo if you fired the gun, the bullet would leave the muzzle at 3000 fps from YOUR frame of reference.  From an object straight in front of the plane that you were shooting at, would see the bullet coming at them at 6000ft per second plus whatever velocity they had moving toward you.\n\nGet it?  Think from the frame of reference!\n\nYou can do it in your car.  At 60mph on the speedometer, what is your speed from your frame of reference.  Zero!  However, that possum in the middle of the road is coming at you at 60mph from YOUR frame of reference.  From the possum's frame of reference he (or she) is moving at zero.  However, the car is coming at the possum at 60mph.\n\nAs for the sound waves, the same principle holds.  They move away from you at 1100 ft/sec from YOUR frame of reference.  You would hear yourself immediately.\n\nHope this explains it.

-It is the fastest of all terrestrial animals and can reach speeds of up to 100 km/h (62 mph) in short bursts.they'd beat the fastest dogs\n\n-Black "tear marks," which run from the corner of its eyes down the sides of the nose to its mouth\nThe fur of the cheetah is yellow with round black spots, which help to camouflage it, and distinctive black tear lines on the sides of the muzzle. The cheetah’s coat is tan, or buff colored, with black spots measuring from ¾ to 1¼ inches across (2–3 cm). There are no spots on its white belly, and the tail has spots which merge to form four to six dark rings at the end. The cheetah's tail usually ends in a bushy white tuft. Cheetahs also have a rare fur pattern mutation: cheetahs with larger, blotchy, merged spots are known as 'King Cheetahs'.\n\n-Unlike true big cats, cheetahs can purr as they inhale, but cannot roar. By contrast, lions, tigers, leopards, and jaguars can roar but cannot purr, except while exhaling\n\n-Cheetah cubs have a high mortality rate due to genetic factors and predation by carnivores in competition with the cheetah, such as the lion and hyena. Some biologists now believe that they are too inbred to flourish as a species.Cheetahs were formerly, and are sometimes still hunted because many farmers believe that they eat livestock\n\n-Cheetahs are carnivores, eating mostly mammals under 40 kg (90 lb), including Thomson's gazelles, and impala. Wildebeest and calves are hunted when cheetahs hunt together. Guinea fowl and hares are also hunted. While the other big cats mainly hunt by night, the cheetah is a diurnal hunter. It hunts usually either early in the morning or later in the night when it is not so hot, but there is still enough light - cheetahs hunt by vision rather than by scent. Prey is stalked to within ten to thirty meters (30-100 ft), then chased. Using their tails to maintain balance, cheetahs can make sharp turns if needed. The chase is usually over in less than a minute and if the cheetah fails to make a quick catch, it will often give up rather than waste energy. Another reason a cheetah may give up is because running at such high speeds puts a great deal of strain on the cheetah's body. The temperature within the cheetah reaches such high temperatures that it would be deadly to continue - this is why cheetahs are often seen resting even after they have caught their prey. Roughly half of their chases are successful. The cheetah kills its prey by tripping it during the chase, then biting it on the underside of the throat to suffocate it, for the cheetah is not strong enough to break the necks of the gazelles it mainly hunts. Then the cheetah proceeds to devour its catch as quickly as possible, for it is unable to defend itself against lions and hyenas.
