Homework Help: Meteor Accelerating towards the Earth

  1. Dec 18, 2011 #1
    1. The problem statement, all variables and given/known data

    a 12 kg meteor experiences an acceleration of 7.2 m/s^2, when faling towards the earth.

    How high above the Earths surface is the meteor?

    2. Relevant equations
    mass of earth= 5.98x1024 kg
    radius of earth= 6.36x106 m



    3. The attempt at a solution

    =7.4x106 m

    =1.06 x106 m above the Earths surface, or 1060 km?

    Does everything look good? Thanks in advance for any help!

    This looks OK.
    Did you realise you did not need the mass of the meteor in the calculation??
