What is acceleration due to gravity of earth?

[6spdtls]

Homework Statement

Earth is not quite an inertial frame. We often make measurements in a reference frame fixed on the Earth, assuming Earth is an inertial reference frame. But the Earth rotates, so this assumption is not quite valid.
Calculate the acceleration of an object at Earth's equator due to Earth's daily rotation, and compare to , the acceleration due to gravity.

Homework Equations

V=2πR/T -> Ar=v^2/r Ar=4π^2r/T^2
Radius of Earth: 6380000m; T=86400s

The Attempt at a Solution

When I plugged my value, Ar(centripetal acceleration) = 0.0337m/s^2
From here, what do I need to do?

I got the answer already lol...it's 0.0337m/s^2 / 9.80m/s^2 = 0.00344g
