    acceleration question!!

    1. The problem statement, all variables and given/known data
    A 4.9 kg object hangs at one end of a rope that
    is attached to a support on a railroad boxcar.
    When the car accelerates to the right, the
    rope makes an angle of 25◦ with the vertical
    The acceleration of gravity is 9.8 m/s2 .
    look at the picture
    2. Relevant equations
    F=ma


    3. The attempt at a solution
    I used the formula to find F of the object, but im not sure how to use the angle given to find acceleration

    Re: acceleration question!!

    Show your work. What forces act on the object? What is the direction of the resultant force?
