Fictional planet Hlipod has a day that lasts $2$ Earth days, and a mass $M\approx 6.018\times 10^{30}\ \text{kg}$. Hlipod has a satellite that is in "geosynchronous orbit," meaning its orbit is circular and the orbital period is the length of a day on Hlipod (so $2$ Earth days). Use Kepler's Third Law to determine the semimajor axis $a$ for the satellite, and thus its orbital radius. Then determine the orbital velocity, using the formula $$v=\sqrt{\frac{GM}{R}}.$$

$a =$
$v =$
