    work done

    An archer, about to shoot an arrow, is applying a force of +240 N to a drawn bowstring. The bow behaves like an ideal spring whose spring constant is 480 N/m. What is the displacement of the bowstring?

    Let the displacement be D, then the required force is:

    F=480.D=240,

    so D=0.5 m.
