I was told that if a plane takes less time to travel from the China to US as opposed to the other direction due to rotation of the earth. I suspect this is incorrect however.
From this scenario I came up with the following thought experiment. Imagine two people sitting on a train. One person is sitting with his back (A) facing the front of the train and the other is facing toward the front of the train (B). They are throwing a ball to one another. They pass by an observer who is standing outside as the train passes (C). How does each person view the ball?
My intuition tells me that (A) and (B) should perceive the speed of the ball the same while (C) should see the ball move faster towards (B) than (A). However some people have told me that time taken for the ball to reach (B) when thrown by (A) should be less than the time taken for the ball to reach (A) when thrown by (B) due to the relative velocity of the speed of the ball and the train. Is this true?
