I dont know if you've seen smallville, but?

Question

I fast would a human have to run that everyone around him or her would apper frozen in time and increase their speed that they could run from North America to Chile in 4 secs?

This is amid towards jillybean & juan d, So what is it's a show i wanted to know the science behind, beside you clearly sound like people who would not understand it if explained to them, plus WHAT the hell are you doing hear the whole point is to answer the question you buffoon!!!!!!!

Answer 1

I like Dr. Greg's solution to disappearing, but let's look at it a bit further, shall we?

Assume the average room is 20 ft X 20 ft.; so the max distance I'd need to whisk out and seemly just disappear would be the diagonal: about 28 ft. So to travel that in "12.5 milliseconds," like Dr. Greg suggests, I'd need to average v = S/t = 28/12.5 X 10^-3 = 2.24 X 10^3 ft per sec while crossing the room and bugalooing out of there. That's better than 1,500 mph (there is a reason they say he travels "faster than a speeding bullet").

Starting from a standing stop, our intrepid hero would need to reach 3,000 mph to average that 1,500 because the average would be v = (v1 + v0)/2 = (3000 + 0)/2 = 1,500. To reach that end velocity, he/she would need to accelerate at a = v/t = (3,000 X 5280)/(12.5 X 10^-3) = 1,267,000,000 ft/sec^2; where 1 mile = 5,280 ft. This is almost 1.3 X 10^9 (that's billion) ft/sec^2

Acceleration due to gravity at Earth's surface is g = 32.2 ft/sec^2; so Superboy is accelerating at n = a/g = (1.3 X 10^9)/32.2 = .04 X 10^9 = 40 X 10^6 g's. In other words, he would be pulling 40 million g's during that escape from the room. But, hey, he's a superlad; so he can take it. But could you...?

Consider the amount of energy the caped crusader expends while getting away in less than the blink of an eye. J = Fd; where J is work in foot-lbs, F is force (ma) in pounds, and d = 28 ft, the distance the big S moves across the room. Thus, we have J = Fd = m(ng) d = mg (n) d = W n d = 220 X 40 X 10^6 X 28 = 246,400 X 10^6 = 246 billion ft-pounds of energy or work. W = mg = Superkid's weight (I'd judge about 220 lbs), n = the number of g's pulled while accelerating (a = ng) up to 3,000 mph.

246 billion ft-pounds of energy (work) is equivalent to 80 tons of TNT; or 160,000 pounds of TNT going off in that room when the super dude splits in less than the blink of an eye. [See source.]

If I were you, I'd not wait for Clark to split...could be hazardous to your health.

Answer 2

if clark ran from kansas to chile, he'd probably have to pass through mexico, brazil etc. i'd estimate this to be about 6000 kilometers. if he can do it in four seconds, that's about 5.4million km/h or 1500km per second. speed of light is 227,000 km per second. not there yet if you ask me.

but if you want to leave quickly without anyone noticing, its best you get out of the room faster than the human visual speed which can detect changes up to 80 times per second. just get out of the room within 12.5milliseconds and all they'll see is a flicker.. and then youre gone. you dont even have to be at the speed of sound.

Answer 3

Dude it's a T.V show for cryin out loud! Besides Supernatural is better!

Answer 4

It's a fantasy..it's not possible
