A helical spring of stiffness k is cut into two halves and a mass m is connected to the two halves.
The natural time period of this system is found to be 0.5 s. If an identical spring is cut so that one part
is one-fourth and the other part three-fourths of the original length, and the mass m is connected to the
two parts. Find the natural period of the system?
