An archer fires an arrow horizontally by pulling the bow string back a distance of 0.47 m before releasing the arrow which has a mass of 0.030 kg The bow and string act like a spring whose spring constant is 439 N/m.

A) While pulling the string back, how much work does the archer do on the system?

B) After the arrow is released, how fast is the arrow travelling when it gets to the point where the bow is stretched 0.27m?
