c) The extension e.

a) Equation for spring constant k is

b)Equation for the extension squared is

(c) Equation for the extension e is

Explanation:

Given;

where;

E is the elastic potential energy

k is the spring constant

e is the extension of the spring

a) Equation for spring constant k is given as.

(b) Equation for the extension squared e2;

(c) Equation for the extension e;
