Can't quite figure out how to start this problem.(adsbygoogle = window.adsbygoogle || []).push({});

If earth's radius is 6378 km and has a period of 24 hrs. find:

a) centripetal acceleration of a particle at the equator.

I did this and got 0.03 m/s^2, but I can't figure out how to start the second part.

b) the centripetal acceleration of a particle at a 60 degree latitude.

and then

c) by what factor would the speed of earth's rotation have to increase for a body on the equator to require a centripetal acceleration of 9.8 m/s^2 to keep it on earth?
