Homework Help: Force Problem, Fuzzy Dice hanging from a rearview mirror

  1. Sep 11, 2008 #1
    1. The problem statement, all variables and given/known data
    Heres the problem, Ive done these kind of problems before but it has been about a year for me since Ive done one and I can't seem to remember how to anymore:
    A pair of “fuzzy dice” hangs from a string attached to the rear view mirror of a race car moving with constant acceleration. Find the acceleration if the string makes a 70° angle with the vertical.

    2. Relevant equations

    3. The attempt at a solution
    I am not sure where to start other than I drew a triangle with a 70 degree angle. If someone could just please give me a place to start off from, I would really appreciate it. Thanks!

    A free-body diagram would a good place to start. Identify all the forces acting on the dice, what can you say about these forces?
