Well, you have to move much faster than 200 mph to be faster than the human eyes.
LeClairity shared this bit of info a while ago:
The question really is - can you move fast enough so that the eye won't perceive you. So, you don't have to move faster than the speed of light as some contributors suggest here - only fast enough so that you're moving faster than the eye's response time.
Think about a movie - the frames are about 24 frames per second, and you can't perceive the flickering. That is for no perception of flicker - the perception limit is maybe around 100-300 Hz depending on person and conditions. So, maybe around a few millisec.
So, lets say you are staring straight ahead, and a 0.25 meter wide person runs past. If they can move that 0.25 meter in 1 millisec, then they will effectively be "invisible". Or about 250 m/s. Then, by the time your eye catches up, the person has moved aready, so there is no overlap.
and
1 mile = 1609.344 meters
1 hour = 3600 seconds
First we find out how many meters per hour:
(250 meters / 1 second) * (3600 seconds / 3600 seconds)
900,000 meters seconds / 3600 seconds^2
900,000 meters / 3600 seconds
900,000 meters / 1 hour
Convert our total meters into miles:
900,000 meters * (1 mile / 1609.344 meters) = 559.235 miles
Therefore 250 meters/sec = 559.235 miles/hour
so if something moved at 559.235 miles/hour, or faster, it would be faster than your eye can perceive unless they saw it coming to or from, like a vehicle on a road or in the air.
but a Person would be a flicker or less.. The main problem is that Mach 1 is 760 mph and something moving that fast causes a physical atmospheric disturbance. A loud one
No, radio waves do not need a medium to travel through. They are a type of electromagnetic wave that can travel through a vacuum, such as space. They can also travel through other mediums, such as air or water.
In theory, to travel back in time, you would need to exceed the speed of light, which is not currently possible based on our understanding of physics. Time travel into the past is still considered a concept mostly explored in science fiction rather than reality.
Light can travel in a vacuum without the need for a medium. This is because light is composed of photons which do not require a medium, unlike other types of waves such as sound waves that do need a medium to propagate.
To identify an image on inclined mirrors, you need to follow the laws of reflection. The angle of incidence is equal to the angle of reflection, so you can trace the path of light rays as they reflect off the mirrors to determine the position and characteristics of the image. Remember that the image formed will appear to be the same distance behind the mirror as the object is in front of it.
To cover 18 miles in 18 minutes, you would need to travel at a speed of 60 miles per hour. This calculation is based on the formula: speed = distance / time.
Yes, you typically need a passport to leave the country for international travel.
im thinkin you need to go hyperspeed
Because it fast and relaxing way to traver
yes
To leave the United States you would need a passport. This is also required for air travel, and land travel.
Yes, a passport is required to leave the United States for international travel.
i am 16 years of age if am leaving Ghana for Russia do i need basic travel allowance
11 kilometers per second.
Yes, anytime you leave the country you do.
You will need to travel at an average of 25 miles ÷ 2 hours = 121/2 mph.
No, you cannot leave the US with an expired passport. You need a valid passport to travel internationally.
We don't have any idea. We are still working on figuring out what we need to travel to Mars. As of 2017 we don't have the technology to leave the Earth's orbit.
