flying around the equator with unlimited fuel @ 500 mph against the spin of the earth how many laps 2 loseaday

Answer 1

Just cross the international date line and you lose or gain a day. In summary, the planet is divided into 24 time zones and there must be a place where a day begins, thus the International Date Line. Travel west across it (gain a day), travel east across it (lose a day).

Answer 2

The diameter of Earth is 7800 miles approximately.
The circumference of Earth is 2*pi*r which mounts to 24490 miles.
The earth travels from west to east with a velocity of 24490/24 hours. which is equal to 1020 miles an hour.

When you fly an aircraft you will be spinning with the Earth during flight and at the same time you have an additional velocity of your own across the surface of the Earth. So if you travel against the movement of Earth that means you are traveling from East to West.

Assuming you are traveling from London, then you would be heading west to the United states.

It will take you 24490/500 = 49 hours to return to the same location from which you started your flight. So you need two full days to make one lap across the Earth.

So you have to travel two full days without stop across the Earth to loose only one day.

Now, on the other hand, you could stand on the international line and have one of your legs on west side of the line and the other leg on the the east side. Then you could start jumping from where you stand and lift you right leg and say now I gain one day, and jump again and lift you left leg and stand on your right leg and say "now I gain one day" or you could just consider my approach as stated hereabove.

Answer 3

I may be overlooking something here, but if you travel westward at 500 mph and the terminator is coming after you at over 1,000 mph, how are you going to lose a day? Seems to me that at 500 mph the best you can do is extend your local day or night.

Answer 4

depends on where you start, and which direction yo are traveling.

If you start in the western hemisphere exactly midway between 0 and 180 degree longitude, either way you travel, it will take exactly 1/4 laps before you cross the international date line into the eastern hemisphere where they are observing the previos day.

if you plan to start on theprime meridian in the western hemisphere and plan on traveling around the western hemisphere to the international date line, it will be 1/2 laps.

if you are in the western hemisphere on very close to either the international date line or the prime merdiain, and you just turn around and cross the one you are near..zero laps.

the eastern hemisphere recognizes the day previous to the day that is currently being recognized by the western hemisphe

Answer 5

What do you mean by lose a day?

Magellan's crew thought it was Sunday when they arrived back at the coast of Spain, but they were off by a day because they didn't consider the implications of daylight falling on different parts of the planet at different times of the day as measured in Spain.

Answer 6

If by "lose a day" you mean it will cause "time travel" into the past?....ain't gonna happen!
