Problem

The following data were obtained for two springs, P and Q: \nSpring P:

0\,\text{N}

causes

0\,\text{cm}

extension and

6\,\text{N}

causes

3\,\text{cm}

extension. \nSpring Q:

0\,\text{N}

causes

0\,\text{cm}

extension and

6\,\text{N}

causes

2\,\text{cm}

extension. \nAssume each spring follows Hooke’s law within this range. a. (a) Which spring has the larger spring constant? b. (b) Calculate the elastic potential energy stored in spring P when it is extended by

3\,\text{cm}

. c. (c) Calculate the elastic potential energy stored in spring Q when it is extended by

3\,\text{cm}

and state which spring stores more energy at this extension.
