Answer:
Eelas = 5 [J]
Explanation:
Elastic energy is associated with the ability that has a spring or any other material with elastic properties.
We can calculate the elastic energy by means of the following equation:
[tex]E_{elas}=\frac{1}{2} *k*x^{2}[/tex]
where:
k = constant spring = 2.5 [N/m]
x = distance stretched = 2 [m]
[tex]E_{elas}=\frac{1}{2} *2.5*(2)^{2}\\E_{elas}=5[J][/tex]
