0.30-kg mass hangs at equilibrium from a spring suspended from a rod. pulling the mass down 4.0 cm from its equilibrium position requires a force of 5.0 n to stretch the spring. letting go of the mass after displacing it 4.0 cm from its equilibrium position, you observe that its amplitude decays to 0.50 cm after 10 oscillations. what is the q of this system? suppose that the system is now driven with a oscillating driving force of f (t) = f_0 sin omega t starting at time t = 0, where f_0 = 0.50 n and the driving frequency f = 2.5 hz. the initial displacement of the mass is, once again, 4 cm below its equilibrium position. find an equation for the subsequent motion of the mass and then plot it as a function of time. what is the steady state amplitude the oscillations? what is the initial period of the oscillations? what is the ultimate period of the oscillations? how much energy is stored in the oscillating system at steady state? how much energy is dissipated per period by the system at steady state?
