1.the Earth rotates west to east.Let say a car with some velocity moving to the direction of rotation of the earth and another car moves with same velocity to the opposite direction of the rotation of the earth.both move for same time(with other condition same for both) then is there the difference in the distance they covered?
The one moving opposite to the direction of rotation must have covered more distance [::)]
2.When a object is dropped from a certain height(Quite enough) on the ground then would the object fall on the same point on the ground from which it has dropped?

Frames of reference comes into play again.
If you're asking if the distance will differ depending on Earths rotation?
No, it won't. Not when compared toward Earths surface.
the second one you need to be more clear on I think.
Are you thinking that as it falls the Earth rotates?
then you're right.
-
If a body falls on the same place then it must have followed the curve path because there is rotaion and revolution at the same time.
-
As long as it is in the air it should be a little less approachable by Earths revolution and so if the fall was long enough fall 'somewhere else' than expected. But when we come to Earth traveling in space, as the solarsystem does too it should still belong to the same frame, but maybe? I'm not sure on that one.
What forces will apply on its gravitational fall in this thought experiment if we disregard friction/air?
All of them? Earths rotation, its path around the sun, the solar systems path, our galaxies path too?
And_???

These due to the reason that we donot know the point of universe or its size ,shape.......
