What is the elastic potential energy of the drawn bow?

An archer pulls the bowstring back for a distance of 0.487 m before releasing the arrow. The bow and the string act like a spring whose spring constant is 341 N/m.

(a) What is the elastic potential energy of the drawn bow?
(b) The arrow has a mass of 0.0329 kg. How fast is it traveling when it leaves the bow?

unrealistic question ( sure you can do the math but a bow varies its energy release over its travel )

Use your standard spring model. 1/2k*x^2 is the energy.

That energy is assumed to be transferred to the arrow
