Ответ:
To solve this problem we will apply Hooke's law. Which says that the force on a spring is equivalent to the product between the elastic constant and the displacement of the spring.
Here,
k = Spring constant
x = Displacement
Rearranging to find the spring constant,
Spring compresses it to 29 cm so
Therefore the spring constant is 215.6N/m
