Answer:
the work required to stretch the spring is 8 J.
Explanation:
Given;
spring constant, k = 2500 N/m
extension of the spring, x = 8 cm = 0.08 m
The work required to stretch the spring is calculated as;
[tex]W = \frac{1}{2} kx^2\\\\W = \frac{1}{2} \times 2500 \times 0.08^2\\\\W = 8 \ J[/tex]
Therefore, the work required to stretch the spring is 8 J.
