# Super problem by Alok

Consider a spring with negligible mass that has an unstretched length $$l_{0} = 8.8 \times 10^{-2} \text{ m}$$. A body of mass $$m_{1} =1.5 \times 10^{-1} \text{ kg }$$ is suspended from one end of the spring. The other end of the spring is fixed. After a series of oscillations has died down, the new stretched length of the spring is $$l = 9.8 \times 10^{-2} \text{ m}$$.

Assuming that the spring satisfies Hooke’s Law when stretched, what is the spring constant?
