The spring's work output while it is not extended is 5 J.
<h3>What is The Hooke's law ?</h3>
According to Hooke's law, as long as the elastic limit is not exceeded, the extension of a particular material is directly proportional to the force applied. Hence, we must be aware of that F = Ke
F = Applied force
Force constant is K.
Extension = e
F = applied force
Force constant is K.
Extension = e
Using the graph
K = F/e
F = 200N
E equals 5 cm or 5 * 10-2 m
K = 200N/ 5 * 10^-2 m
K = 4000 N/m
Now;
Work = 1/2Ke^2
Work = 0.5 * 4000 N/m * (5 * 10^-2 m)^2
Work = 5 J

Answer:
It is one of the strongest materials in the world and can hold anything
There is no work because there is no displacement
answer: 0
Because metric units use the deca system, 1km = 1000m = 100 000cm etc...
