A pen contains a spring with a springconstant of 295 N/m. When the tip of thepen is in its retracted position, the spring iscompressed 5.20 mm from its unstrainedlength. In order to push the tip out and lock itinto its writing position, the spring must becompressed an additional 6.90 mm. Howmuch work is done by the spring force toready the pen for writing? Be sure to includethe proper algebraic sign with your answer.NumberiUnits
