For the system shown in fig.1-38, the block has a mass of 1.5 kg and the spring constant k = 8.0 N/m. Suppose that the block is pulled down a distance of 12 cm and released. If the friction force is given by -bv, where b = 0.23 kg/s, find the number of oscillations made by the block during the time interval required for the amplitude to fall to one-third of its initial value.
