Assignment:
Hooke's law states that the relationship between the stretch s of a spring and the weight causing the stretch is linear. For a particular spring, a 5-pound weight causes a stretch of 2 inches, while with no weight, the stretch of the spring is 0.
(A) Find a linear equation that expresses s in terms of ω.
(B) What is the stretch for a weight of 20 pounds?
(C) What weight will cause a stretch of 3.6 inches?
Provide complete and step by step solution for the question and show calculations and use formulas.
