A massspring system has a frequency of 4 Hz When the mass is

A mass-spring system has a frequency of 4 Hz. When the mass is decreased by 0.25 kg, the frequency is changed by 20%. Determine (2.a) the mass m, and (2.b) the spring constant k(N/m) for the original system

The value of mass for this mass spring system is 14newton .

The value of spring constant k is 13 n/ m .
