Awesome. Thanks for that! I truly am rusty. However, leaving it a couple of weeks and looking at some electromag for a while made it a lot easier with fresh eyes. Your help was much appreciated!
So, plugging 2) into 1) gives:
Fsm + Fem = (Mm x Ame) + (Mm x Aes)
Then eliminating Fem = Mm x Ame
gives Fsm = Mm x Aes
If you assume Aes ≅ Ams (given A = V2/R and that Res ≅ Rem)
All good? I feel like that was too easy.
Homework Statement
Given
if:
(1) Fsm + Fem = Mm x Ams
(2) Ams = Ame + Aes
(3) Res ~= Rms
Show that (4) Fem ~= Mm x Ame
Where:
'Fsm' is the force between the sun and moon, 'Fem' the force between Earth and moon, etc.
'Mm' is the mass of the moon, 'Ams' the accelleration of the...
