Problem
The following data were obtained for two springs, P and Q:
Spring P: 0N causes 0cm extension and 6N causes 3cm extension.
Spring Q: 0N causes 0cm extension and 6N causes 2cm extension.
Assume each spring follows Hooke’s law within this range.
(a) Which spring has the larger spring constant?
(b) Calculate the elastic potential energy stored in spring P when it is extended by 3cm.
(c) Calculate the elastic potential energy stored in spring Q when it is extended by 3cm and state which spring stores more energy at this extension.
