Consider a tall building located on the Earth's equator. As the Earth rotates, a person on the top floor of the building moves faster than someone on the ground with respect to an inertial reference frame because the person on the ground is closer to the Earth's axis. Consequently, if an object is dropped from the top floor to the ground a distance h below, it lands east of the point vertically below where it was dropped. (a) How far to the east will the object land? Express your answer in terms of h, g, and the angular speed w of the Earth. Ignore air resistance and assume the free-fall acceleration is constant over this range of heights. Ax = (b) Evaluate the eastward displacement (in cm) for h = 52.0 m. cm (c) In your judgment, were we justified in ignoring this aspect of the Coriolis effect in our previous study of free fall? O Yes O No (d) Suppose the angular speed of the Earth were to decrease with constant angular acceleration due to tidal friction. Would the eastward displacement of the dropped object increase or decrease compared with that in part (b)? O increase O decrease
