How fast does a satellite move?

Level 2

A satellite is said to be in geosynchronous orbit if it rotates around the earth once every day. For the earth, all satellites in geosynchronous orbit must rotate at a distance of 4.23×107 meters from the earth's center. What is the magnitude of the acceleration felt by a geosynchronous satellite?

.224 m/s2 3076 m/s .3 m/s2 A= v/r2

The acceleration felt by any object in uniform circular motion is given by

. We are given the radius but must find the velocity of the satellite. We know that in one day, or 86400 seconds, the satellite travels around the earth once. Thus: Thus
