    An archer pulls the bowstring back for a distance of 0.470 m before releasing the arrow. The bow and string act like a spring whose spring constant is 425 N/m.
    (a) What is the elastic potential energy of the drawn bow?
    (b) The arrow has a mass of 0.0300 kg. How fast is it traveling when it leaves the bow?
