Problem: When you look up into the sky, you always see the same part of the moon, no matter what time of the month or year it is. In order to achieve this, the rotational period of the moon must be equal to its orbital period (how long it takes to orbit the Earth). Given this fact, what is the angular velocity of the moon due to its spinning about its own axis?
