Hi all, I have the following problem which I have tried to solve for a very long time, very very long time indeed- 2 or more years. I am studying here all by myself and I got no one to help me. I shall not participate in any talk. I have had enough with it. this problem is in the Schaum's Book "Theoretical Mechanics" by Moray Speigel, Chapter 6, Moving Coordinate Systems. Here it is: A river of width D flows northward with a speed vo at colatitude \lambda. Prove that the left bank of the river will be higher than the right bank by an amount equal to: (2D\omega vo cos \lambda)(g^2 + 4 \omega^2 vo^2 cos^2 \lambda)^-1/2 where \omega is the angular speed of theearth about its axis.
