  1. Nov 22, 2011 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    ?


    3. The attempt at a solution

    a) y=2Lcos(θ)
    x=2Lsin(θ)

    b) vgrebfgd.png

    I haven't started the next question as I want to make sure the active force diagram is correct first..


    If somebody could just check the diagram and help me with where I'm going wrong if I have done.
