Enjoy, and I am available for tutoring and private classes! :)
Suppose that 2J of work is needed to stretch a spring from its natural length of 30cm to a length of 42cm.
(a) How much work is needed to stretch the spring from 35cm to 40cm ?
(b) How far beyond its natural length will a force of 30N keep the spring stretched?
