Find car's acceleration based on a die's angle

  1. Oct 2, 2011 #1
    1. The problem statement, all variables and given/known data
    A fuzzy die hanging from a string of a car's rear view mirror is deflected 15 degrees from the vertical. what is the car's acceleration if the die's mass is 250g


    2. Relevant equations
    basic forces equations
    trig


    3. The attempt at a solution

    You have an error in Fx ????

    if that is a triangle with a 15o angle, then the opposite side is not what you said - much smaller. The hypotenuse isn't that big either ????

    Other than that, your reasoning is good.

    EDIT: looks like you used 20o

    ahh right, the calculations are wrong, but is the method right?
