Exam question

  1. May 3, 2012 #1
    1. The problem statement, all variables and given/known data
    This was a question on my test. I had to choose the direction of the acceleration vector for each position. I was wondering if I chose the correct answers.

    2. Relevant equations

    a = gsinθ

    Ʃ[itex]F_{y}[/itex] = [itex]N_{1S}[/itex]( normal force) - [itex]W_{1E}[/itex] ( weight force)

    3. The attempt at a solution

    for position one I picked 4
    for position two I picked none (there was an option for that)
    for position three i picked 3
