I am having trouble trying to figure out this problem:
Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: w=Cr^-2, where C is a constant, and r is the distance that the object is from the center of Earth.
Solve the equation for r.
I believe that I would multiply by r^2: wr^2=C
then divide by w: r^2=C/w
but then I am lost, also I am confused because the equation is using r raised to the -2 power.
Could someone help me understand what I am doing wrong or missing?
Thank you.
