Answer 2

Answer: (question is incomplete)

Step-by-step explanation:

Net external force is zero at equilibrium. So to

calculate extension at that point

mg = kx which gives x = mg / k

The block still has some velocity in this position. So it

moves further down till the velocity becomes zero. This maximum extension is

given by

1/2 k * x (max) * x (max) = mg * x (max) [energy

conservation]

it gives x (max) = 2 mg / k

So extension at equilibrium is mg / k
