What if a chopper flies over Beijing 200 mtrs from ground, does not move stays there, where it will be after the lapse of 12 hours and why?

Doesot move in relation to what? If it stays stationary in relation to the earth it will move at the same speed and direction of the Earth's rotation. If not it will end up the other side of the world and would have effectively moved at over 1000mph (in relation to Earth) to have got there, assuming that it was near the Equator to start with.

Don't agree SOTHC. If that were true 'planes wouldn't get off of the ground! (Thort a little bad grammer would add to the levit1) Location of Beijing, China, 39, 55 N, 116, 25 E.  Circumference of Earth = 40,000 kilometers  Time for one rotation = 24 hours  12 hours = 20 000 km = half the distance  Degrees around earth = 306 o  Half the distance = 180 o  180 degrees less 116.25 Beijing's location = 63.75 degrees   Helicopter remains constant . Earth revolves 20, 000km  The helicopter would be in the Atlantic Ocean East of Atlantic City, New Jersey and north of Bermuda on that little blue colored area on my atlas. "Getting á suntan man!" Check it out! (Atlantic City USA 39° 23' N 74° 26' W Beijing China 39, 55 N, 116, 25 E.) Are you going to the Beijing olympics ? May 04 05, 2:54 AM
