Problem 1... Thank you!

Answer 3

I'm sorry for taking so long with a solution for this. I started the problem and got partially done then I checked my work with the answer key and cannot figure out what they did to simplify for the g of europa. My work so far is attached

Answer 4

jmerson is the G my itself in the answer?

Answer 5

they somehow reduced it to:

\[g_{eur}=\frac{R_{eur}}{R_{ear}}g_{ear} = \frac{1}{4}g_{ear}\]
