A steel ball of mass 10 kg attached to a vertical spring is having a damped oscillation. The spring constant is 2 x10* N/m while the damping coefficient from air resistance is b=3.0 Ns/m. a) Calculate the frequency of the damped oscillation. [4 marks] b) Determine the percentage of decrease for amplitude of oscillation in each cycle. (Hint: Use decremented amplitude with motion) [4 marks] c) Find the time interval that elapses while the energy of the system drops to 5% of its initial value.
