The space shuttle A is in an equatorial circular orbit of 240-km altitude and is moving from west to east. Determine the velocity and acceleration which it appears to have to an observer B fixed to and rotating with the earth at the equator as the shuttle passes overhead. Use R = 6378 km for the radius of the earth. Also use Fig. 1/1 for the appropriate value of g and carry out your calculations to four-figure accuracy.
