How Do You Calculate Centripetal Acceleration for Earth Movements?

[ElectroNewby]

Homework Statement

1) Calculate the module of the centripetal acceleration of an object located on the equator for its movement linked to the rotation of the Earth on itself.

2) Calculate the module of centripetal acceleration by its orbit around the sun (if we consider it's orbit as circular).

Homework Equations

T=2 pi / v ?

The Attempt at a Solution

T=2 pi / v :(
