A ball is dropped from a tower of height h located at the equator. How far to the east is the ball deflected by the time it hits the ground? Denote with (omega)E the (magnitude of the) angular velocity of rotation of the Earth and work up to linear terms in (omega)E only. Solve the problem in two different ways: i) from the point of view of an observer in the non-inertial reference frame attached to the Earth, and ii) from the point of view of an observer in an inertial reference frame.
