Homework Statement

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

Homework Equations

ac = v2/r

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.
