Question

A block is suspended by an ideal spring of force constant k. If the block is pulled down by applying a constant force F and if maximum displacement of block from its initial mean position of rest is x, then :
:

1) increase in energy stored in spring is kx nod square
2)x nod = 3F/2k
3)x nod =2F/k
4) work done by applied force F is Fx nod​

Answer 1

Answer:

So sorry I did not get this answer but I have been working on the questions so I will not be able to get back to you sooner

Answer 2

Explanation:

On applying energy conservation. Energy stored in the spring must be equal to the work done by the force.
