Spring is first stretched-unstressed length

Reference no: EM13660863

A spring is first stretched 2.0 cm from its unstressed length. It is then stretched extra 1.8 cm. How does the work needed for the second stretch compare to the work required for the first stretch (give a ratio of second to first)? (Be sure you are comparing the work done to stretch the spring, not the net work.)
