A 4.kg mass is attached to a spring hanging from the ceiling. thereby causing the spring to stretch 80 cm upon coming to rest at equilibrium. At fime t=0, the mass is displaced 5 cm below the equilibrium position and released. At this same instant, an external force F(I) 0.3 cost N is applied to the system. If the damping constant for the systom is 5 N-secm, determine the equaton of motion for the mass. What is the resonance frequency for the syatem? What is the equation of motion for the mass?
The resonance frequency for the system is (Round to four decimal places as needed.)
