Homework Help: Circular motion problem

  1. Mar 1, 2006 #1
    "show that a point on the surface of the earth at latitude theta from the equator has an acceleration of magnitude 3.37cm/s^2*cos(theta) relative to a reference fram not rotating with the earth."

    i really have no idea how to approach this problem. i don't really understand why the acceleration at a point above or below the equator should be different than the acceleration at the equator. could anyone provide a hint or two as to how i should start?

    many thanks.

    Hint1: Centripetal acceleration.
    Hint2: Distance from the axis of rotation.
