HOW DID IT HAPPEN???


Best Answer bonanova, 24 September 2007 - 03:12 AM

I think this answer

Yep. I presume you mean 1 mile north of south pole?

doesn't work: when you get to the South pole, how do you run West?

But this answer:

There's an infinite number of circles around the South Pole where he could have started.

does: for example, any point on the circle (1 + 1/2pi) miles from the South Pole.

After going South 1 mile, you're (1/2pi) miles from the Pole,
which allows you to run West 1 mile [1 lap of a 1-mile circumference circle]
and be able to go a mile North to the starting point.

As Martini noted, there is an infinite number of starting distances:
1 + 1/2Npi miles North of the South pole where N is any positive integer.
N is then the number of circular laps in your westerly mile.

e.g. N=5280 - you'd run 5280 laps around a 1-foot circumference circle.

Here's a counter question - why can't N be negative?
i.e. start closer than a mile - you could still do N laps Go to the full post

I should correct my last , the latitude is in fact 89º 59.84´ and corresponding 89º 58.84´ ( I was using full diameter to calculate instead of radius)

Assumin that he only ran and didnt get anything else it has to be the north poll becase anywhere else he would have to go east in order to get back to where he started.

Had he gotten a help from something else there is infact an infinate possibity of where he started

I THINK HE STARTED AT THE NORTH POLE AND RAN SOUTH 1 MILE AND THEN WEST THEN NORTH BACK TO THE POLE AND THERE IS AN INFINITE NUMBER OF STARTING DIRECTIONS IF HE WAS TO MOVE THE SMALLEST DISTANCE POSSIBLE FACING SLIGHTLY WEST FROM THE PREVIOUSLY FACING POSITION TO THEN START AGAIN HEADING SOUTH THEN WEST THEN NORTH AND OVER AND OVER FOR ETERNITY SINCE IT WOULD BE AN INFINITE NUMBER OF STARTS.

IF HE WAS TO START 1 MILE NORTH OF THE SOUTH POLE THEN WHEN HE GO TTO THE SOUTH POLE TO GO WEST HE WOULD BE PIVOTING ON ONE FOOT DIRECTLY OVER THE POLE AND SPINNING WITH THE OTHER FOOT FOR ONE MILE AND HE WOULD QUICKLY BE STANDING IN A BIG PUDDLE ON THE SNOW OR ICE BECAUSE HIS SHOE OR BOOT THAT WAS PIVOTING OVER THE SAME SPOT ON THE POLE WHILE TRAVELING WEST WOULD HEAT UP FROM THE CONSTANT FRICTION IN THE SAME SPOT FOR THE ENTIRE MILE...

I DUNNO THE NORTH POLE SOUNDS RIGHT TO ME THO!

I DONT HAVE TIME TO MAKE A DIAGRAM TO BETTER EXPLAIN RIGHT NOW, SORRY
