A 9.60 kg object oscillates at the end of a vertical spring that has a spring constant of 2.00 104 N/m. The effect of air resistance is represented by the damping coefficient b = 3.00 N·s/m.
(a) Calculate the frequency of the dampened oscillation. (Hz)
(b) By what percentage does the amplitude of the oscillation decrease in each cycle? (%)
(c) Find the time interval that elapses while the energy of the system drops to 2.00% of its initial value. (s)
