    Here is what I recomend:

    A. Write down what the question is asking

    B. Write down what are the knowns

    C. Write down what are the unknowns

    D. Write down which method you will try to use to solve this (Energy, kinematic?, and why)

    E. Write down the equations you have based on the method chosen from part D.

    F. Try to manipulate the equations to get a solution

    G. Check your solution to see if it seems too big or small to be reasonable

    (Do make a picture too)

    Agreed except for F.

    Determine the correct equation, manipulate units to verify. Make sure it works graphically, the picture.

    That sounds like a good idea.
