(a(i))[2]
Explain what damping means.
(a(ii))[2]
Suggest, with a reason, whether the damping is light, critical or heavy.
(b(i))[1]
Use Fig. 2.2 to find the frequency of vibration of the mass.
(b(ii))[2]
Hence show that the initial energy stored in the steel strip before the mass is released is about $3.2\,\text{mJ}$.
(c)[2]
After eight complete oscillations of the mass, the amplitude of vibration falls from $1.5\,\text{cm}$ to $1.1\,\text{cm}$. State and explain whether, after a further eight complete oscillations, the amplitude will be $0.7\,\text{cm}$.
