Homework Help: Centripetal acceleratation

  1. Mar 26, 2007 #1
    1. The problem statement, all variables and given/known data
    The problem states: Find the centripetal acceleration of a point on the Equator. Find the centripetal acceleration at North Pole, due to the rotation of Earth about its axis


    2. Relevant equations
    ac = v2/r


    3. The attempt at a solution

    Well I tried to make an attempt to this problem, but I don't know where to begin. All I have is the radius of the earth which is 6 x 10 to the 6 power m (meters). This may seem like an easy problem, but I can't seem to comprehend physics at all and I would appreciate it a lot if I could get help, Thanks.

    All you need now is a v. What is it at the North Pole? How would you find the earth's rotational velocity at the equator? Velocity=distance/time.
