Homework Statement



What is the centripetal acceleration of the Moon? The period of the Moon's orbit about the Earth is 27.3 days, measured with respect to the fixed stars. The radius of the Moon's orbit is
RM = 3.85 · 108 m.

Homework Equations



a = V^2/R

V = 2*pi*R/P

The Attempt at a Solution



Centripetal acceleration in a circular orbit of radius R is
a = V^2/R

You can get V from the orbit radius, R, and the period, P.

V = 2*pi*R/P

Make sure P is in seconds when you compute V.
