44 Sq.Ft. per second is not a speed, it's an area per time.
And rotation is measured as an angle per time. The Earth rotates about 15 degrees per hour.
At the equator, the rotation speed is about 1038 miles per hour, which is 1522 feet per second.
Unless you get to the 8th decimal place, the acceleration is practically zero.

The equatorial circumference is about 24902 miles, so to get its speed in miles per hour, you divide by 24, then knock off 1 part in 365.25 (because in 24 hours we make one full turn, plus one day's worth of the extra turn that we have to make in a whole year). It comes to 1035 miles per hour, or 1518 feet per second.

Because the Earth is not a sphere but rather an oblate spheroid, the circumference varies according to where it is measure. At the equator it is 24,901.55 miles. The other measurement (around the poles) is 24,859.82 miles.

1070 mph at the equator.
