Orbital speed & time required

  1. Apr 13, 2009 #1
    1. The problem statement, all variables and given/known data
    the solar maximum mission satellite was placed in a circular orbit about 150 miles above earth. Determine (a) the orbital speed of the satellite and (b) the time required for 1 complete revolution


    2. Relevant equations



    3. The attempt at a solution

    But you haven't shown an attempt yet! Here's where I would start:

    The force of gravity between the satellite and the earth provides the centripetal force.
    Fg = Fc
    What should we do from here?

    try thinking about newtons laws of motion and applying one of them in particular radially =]
