How to prove this connection

  1. Nov 9, 2008 #1
    1. The problem statement, all variables and given/known data
    I have to prove in a conservation of energy question

    T-W =(mv^2)/L




    How could I go about starting this?

    Well, you can do this:

    [tex]\vec{T} = \vec{W} + m\vec{v}^2/\vec{L} = m\vec{g} + m\vec{g}\vec{L}(1-\cos\theta) = \vec{W}\vec{L}(1-\cos\theta)[/tex]. I'll leave the conclusion up to you to resolve.
