Why rockets are launched from west to east in the equatorial plane?

A train 1 moves from east to west and another train 2 moves from west to east on the equator with equal speeds relative to ground. The ratio of their centripetal accelerations (a_(1))/(a_(2)) relative to centre of earth is:

The acceleration due to gravity at the equatorial plane is

Statement-1: Space rockets are usually launched in the equatorial line from west to east. Statement-2: The acceleration due to gravity is minimum at the equator.

An artificial satellite of the earth is launched in circular orbit in the equatorial plane of the earth and the satellite is moving from west to east. With respect to a person on the equator, the satellite is completing one round trip in 24 h . Mass of the earth is M=6xx10^(24)kg. For this situation the orbital radius of the satellite is

Assertion: Space rockets are usually lauched in the the equitorial line from west to east. Reason: The acceleration due to gravity is minimum at the equatore.

Two satellites going in equatoral plane have almost same radii. As seen from the earth one moves from east to west and the other from west to east. Will they hav the same time period as seen from the earth? If not which on will have less time period?

A car runs east to west and another car B of the same mass runs from west to east at the same path along the equator. A precess the track with a force N_(1) and B presses the track with a force N_(2) . Then
