A spring is 10 cm long when not stretched. If it takes 120 N to stretch it from its resting position of 10 cm to a position of 35 cm, how much work is done to stretch it that far?
(I have this question in math but I need to solve it using the Hooke's law which is physics and then set up the integral. After that I will need to use the Fundamental Theorem of Calculus)
