An engineering device can be modeled as a simple spring-mass system. Given the natural frequency of the system is 62.83 rad/s. An experiment has been conducted to study how the change of stiffness affects the dynamic properties of the system. The finding shows that the natural frequency is changed to only 55 % of the original frequency when the spring constant is reduced by 800 N/m. Calculate the mass and the spring constant of the original system. An engineering device can be modeled as a simple spring-mass system. Given the natural frequency of the system is 62.83 rad/s.
