    You can start with the equations you know

    a=v^2/r = (2pi*r/T) ^2/r = 4pi^2r/T^2

    Radius of earth (R) = 6378.1 km

    Time in one day (T) = 86400 seconds

    Latitude = 44.4 degrees

    If you draw a circle and have the radius going out at a 44.4 degree angle above the center you can then find the r.

    r=Rcos (44.4)

    r=6378.1cos (44.4)

    r = 4556.978198 km or 4556978 m

    Now you can plug this value into the acceleration equation from above ...

    a = 1.8*10^8/7.47*10^9

    a =.0241 m/s^2
