Answer:
Explanation:
A Spring stretches / compresses when force is applied on them and they are governed by the Hookes Law which states that the force required to stretch or compress a spring is directly proportional to the distance it is stretched.

F is the force applied and x is the elongation of the spring
k is the spring constant.
negative sign indicates the change in direction from equilibrium position.
In the given question, we dont have force but we know that the pan is hanging. We also know from the Newton's second law of motion that

Inserting this into Hooke's Law

computing it for x,

This is the model which will tell the length of the spring against change in the mass located in the pan.
<span>A pulley is able to do that.</span>
The mass is moving by uniformly accelerated motion, with initial velocity

and acceleration

. Its position at time t is given by the following law:

where we take the initial position

since we are only interested in the distance traveled by the mass.
If we put

into the equation, the corresponding time t is the time it takes for the mass to travel this distance:


And the two solutions for the equation are:

--> negative, we can discard it

--> this is the solution to our problem
