A 11.9-kg object oscillates at the end of a vertical spring thathas a spring constant of 1.80 ✕ 104 N/m. The effect ofair resistance is represented by the damping coefficient
b = 3.00 N · s/m.
(a) Calculate the frequency of the damped oscillation.
Hz
(b) By what percentage does the amplitude of the oscillationdecrease in each cycle?
%
(c) Find the time interval that elapses while the energy of thesystem drops to 3.00% of its initial value.
s
