## Homework Statement

A 12 kg meteor experiences an acceleration of 7.2 m/s2, when falling towards the earth.

a) How high above the earth’s surface is the meteor?

1.06x10^6

b) What force will a 30 kg meteor experience at the same altitude?

216 N

## Homework Equations

I was comparing question b) with a friend and we both got the same answer however, we both had different solutions on solving it. My friend used [Fg= mg] while I used [Fg= Gm1m2/r^2] (m1 is m subscript 1 and m2 is m subscript 2.)

So my question is, does it matter which formula I use?
