Geostationary orbits can be achieved only very close to the ring 35,786 km (22,236 mi) high, directly above the equator. This equates to an orbital velocity of 3.07 km/s (1.91 mi/s) or a period of 1436 minutes, which equates to almost exactly one sidereal day or 23.934461223 hours.
It takes roughly 365 days for the Earth to go around the Sun once. This means that the Earth is rushing through space around the Sun at a rate of about 67,000 miles per hour.
So convert 3.07 km/s and 67,000 mph into m/s and those are your answers.
