An 0.10 kg object is hanging from your rearview mirror. While you are accelerating 4.0 m/s2 the string makes an angle with the vertical. There is a weight force going down and tension force along the string. What is the tension force and the angle?

    Let the tension force be T and the angle be A. Vertical and horizontal force balance equations tell you thatL

    T cos A = m g
    T sin A = m a

    Divide the secnd equation by the first.

    tan A = a/g

    a = artan a/g

    Now solve for T
    Hint: Add the squares of each of the first two equations
