Arotating satellite has the same angular velocity as the earth. if the satellite is 5x10^7 m from the center of the earth, what is its tangential velocity

We will want to be using radians for this question so that we can calculate arc lengths easily.

The angular velocity of the earth is

The satellite tangential velocity is the distance from the earth times the angular velocity, which is


For meters per second, we divide by the number of seconds in an hour, which is 3600:
