no, he's not an organ donor. No it was the arm of the sender. It was not a bet. A test of loyalty comes close.
clue 1: The 3 men know eachother; they sailed on the same ship.
Clue number 2:The arm belonged to the original sender.
3rd clue: The South-African guy and the Japanese guy also only have 1 arm.

So, the SA and the J gave their arms to save the life of the sender and the sender promised to give his in return.But why 2 guys on a ship would lose their arms and why the third didnt loose his...You said sail so a transplant its irrational besidesssss....beats me!
I accept this answer as correct.
They got shipwrecked together on a deserted island with no food, and agreed to eat parts of themselves (an arm). When the first 2 were eaten, they were saved.
The 3rd person showed the other 2 he was keeping his promiss.
Garbarsardar.jr has it !!

Almost...
There are ten sacks of gold coins. The one has fake coins. You know that a fake coin is 1 gram lighter then a real one and you have at your disposal scales and a multitude of counterweights.You can use the scale only once.Hoe will you discover the sack with the fakes?

Would changing anything on the scales be considered "using it more than once"?
Sack 1: 1 coin, Sack 2: 2 coins, sack 3: 3 coins , sack 4: 4 coins and sack 5: 5coins. Place them on the left side of the scales.
Sack 6: 1 coin, Sack 7: 2 coins, sack 8: 3 coins , sack 9: 4 coins and sack 10: 5coins. Place them on the right.
If the right side weighs 4 grams more, than the left side has 4 coins which are too light: hence sack 4 is the false-coin sack.

OK: new quiz-question.
A couple of children are teasing a dog. They tie a tin to his tail. They release the dog and the frightened dog walks away with a speed of 1 m/s. When the tin hits the ground after 1 second, the dog is frightened of the noise and doubles his speed. The tin hits the ground again, 1 second later and the dog hears this and doubles his speed. The tin continues the hit the ground every second, and upon hearing this, the dog doubles his speed.
The poor animal runs all the way from Amsterdam to Istanbul (~3000 km). At which speed does the dog arrive at Istanbul ??

Trying to be good.

Does that mean he stopped at Istanbul? If so, his speed is zero.
(If I'm right, someone else can go)

No you're not right. Let's say the animal was stopped in the centre of Istanbul (3001 km) and I want to know the speed at 3000 km.
Good try, but wrong.

I dont mean to be rude or anything, but this is a trick-question thread, and mathematical problems (unless they have a twist in the tail) aren't really trick questions.

If I understood the question correctly, and it is not a trick question, I think the anwer would be 2097152 m/s.
I used excel to solve this.
Also, it would take him 22 seconds to complete his journey.

I get the same answer as Yaniv.
Do we have to take into account the effect of gravity? At a certain speed, the KE of the tin due to the dog's velocity will equal the PE due to gravity, so the tin won't hit the ground. I believe it is at 11.2 km/s. At this velocity, the dog will be in "orbit" just above ground level and reach Istanbul at 11.2 km/s.

Which isn't a power of two - the first possible speed over that would be 16m/s.
Edit: The above makes no sense, ignore it. Funny how those 'kilo' things evade you. Such small letters. Still, there will indeed be a point at which said tin will no longer touch the ground, but air resistance and the length of the string will be factors, too..

Which means that he flies over Istanbul 
But anyway, he couldn't get past 11.2km/s, because if he did, he would float away, and not be able to sustain his speed for very long (he can't touch the ground to run) due to the very high air resistance he would feel. So he would fall back to Earth at slightly less than 11.2km/s, at which time he'd increase his speed again, etc. etc. etc. so he'd just stay at 11.2km/s.
Oh, and it's 16,384m/s

No, at 16,384m/s he would have traveled 32,767 meters which is equal to 32.767 Km.
