Let's first find the stretch of the spring from the Hooke's Law:
here, "F = mg" is applied force (the force of gravity), "k" is the spring constant and "x" is stretch of the spring.
Then, we get:
To find the answer, we need to add up the elongation and the initial position of the end of the spring:
Answer:
"x_{end} = 59 cm."
