a) write a formula for this relationship.

b) at what height will the acceleration due to gravity be 6 m/s^2?

---------

I do not know how to approach this question because.. well all I know is that this function needs to be a rational function because this is the topic we are on. Please help and describe why you are doing the steps. Thanks in advance!!

where

d= distance in km,

g= acceleration in m/s^2

Use the following relationship to find K

g(7000)=8.2 m/s^2

then use the calculated value of K to find

g(x)=6 m/s^2

then use the calculated value of K to find x, where x is the distance from the centre of the earth to be found.

g(x)=6 m/s^2
