Ok, so if a ball is thrown vertically upward with velocity v on the earth's surface. (Air resistance being neglected). I have to show that the ball lands a distance (4wsin(beta)v^3/3g^2) to the west where w is the angular velocity of the earth's rotation and beta is the colatitude angle. fIhave equations for the centrifugal force where Fcf=-mw x (w x r) for the Coriolis force where Fcor=-2mw x v and through this should be able to solve this equation which goes something like F=mg +Fcor +Fcf where F=mass multiplied by the acceleration of coordinate system. Help anybody?
