1. The problem statement, all variables and given/known data A 12 kg meteor experiences an acceleration of 7.2 m/s^2, when falling towards the earth. a.) How high above the earth's surface is the meteor? b.) What force will a 30 kg meteor experience at the same altitude? 2. Relevant equations Fg = ma , Fg =Gm1m2 / r^2 3. The attempt at a solution a = Fg / m, thus: Fg / m = Gm1m2 / r^2 then: r = √ (Fg / Gm1m2(m)) I got this far, somewhat understanding what I was doing the equation manupulation. Please help me! I searched this question up, but that thread was not helpful. I don't know how to solve the question. The altitude is the radius from the earth? and since a = Fg / m, :S I equated this with the Fg = Gm1m2 / r^2, :|. Please help!
