Consider formula A to be v = StartFraction 2 pi r over T EndFraction and formula B to be v2 = GStartFraction 2 pi r over T EndFr
MissTica

Answer:

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
