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.
