Calculus  Hooke's Law , Spring Constant
posted by janet .
Hi could someone please help me answer this question:
It requires 0.05 joule of work to stretch a spring from a length of 8 cm to 9 cm and another 0.10 joule to stretch it from 9 cm to 10 cm. Determine the spring constant and find the natural length of the spring.
Thank you
