    Answer:

    14°

    Explanation:

    From the question; we are being told that the pendulum swings through a total displacement of 28°,we are to assume  that  the displacement is equal on each side of the equilibrium position.

    So; the amplitude of the vibration literally reflects the maximum displacement generated by a moving body, its wave is usually measured from the equilibrium position which equal to one-half of the length of the vibrating path. Having said that; the amplitude of this vibration is one-half displacement of the pendulum

    i.e

    A = \frac{1}{2} of 28°

    A = 14°
