We the Period T we can find the constant k,
That is
We delete the squart root elevating squareing everything,
M is the hanging mass, m is the spring mass,
k is the spring constant and T the time period
a) So for the equation we can compare, that is,
Here x is the hanging mass M, so comparing the equation we know that
b) For the mass of the spring we make similar process, so comparing,
