Given that the Moon's period about the Earth is 27.32 days and the distance from the Earth to the Moon is 3.84*10^8 m estimate the mass of the Earth. Assume the orbit is circular. Why do you suppose your estimate is high?
The force of attraction= centripetal force
G MeMm/d^2=Mm*V^2/d
but v= 2PId/T
put that in for v in the above, solve for Me.
v= 2PId/T
what does PI mean?
PI is 3.14...
