Homework Help: Newton's second law

  1. May 24, 2010 #1
    1. The problem statement, all variables and given/known data
    How can Newton's 2nd law be derived for a single body in an 1Dimesional case ?


    2. Relevant equations
    F=m(du/dt)

    3. The attempt at a solution
    It is given that the principle of conservation of energy must be used,for the derivation.
    Are there any more hints?
