suter [353]
The formulas that will be used are:

Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.

Gravitational force = GMm /r²
Centripetal force = mv²/r

Equating,
GMm/r² = mv²/r
v² = GM/r

The first scenario will use the formula v² = GM/r


Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.

v = 2rπ/t
