Inverse means one thing changes the opposite way anothe thing changes.
If something gets bigger, then something else gets smaller...and so forth.
What this is saying is that the further you go from the Earth, the lighter
you become. Weight is inversely proportional to the square of the
distance means as the distance(and thus the square of the distance) gets
larger, the weight gets smaller. You know that already. It's common
knowledge that if you go into outer space you'll float around. Right?.
When you set up proportions, find the value of k first using the initial
conditions given, then sub it into the formula.
\(\displaystyle y=\frac{k}{x}\)
Find k.
\(\displaystyle 1000=\frac{k}{4000^{2}}\)
Now, solve for k and divide it by \(\displaystyle 4500^{2}\)
You could just set it up as:
\(\displaystyle \frac{x}{4000^{2}}=\frac{1000}{4500^{2}}\), solve for x.
