A spring on a horizontal surface can be stretched and held 0.2 m from its equilibrium position with a force of 16 N. a. How much work is done in stretching the spring 3.5 m from its equilibrium position? b. How much work is done in compressing the spring 2.5 m from its equilibrium position?

a  

b  

Explanation:

Generally the force constant is mathematically represented as

substituting values given in the question

=>  

=>  

Generally the workdone  in stretching the spring 3.5 m is mathematically represented as

=>    

=>    

Generally the workdone  in compressing the spring 2.5 m is mathematically represented as

=>
