For the system shown in down Fig., the block has a mass of 1.52 kg and the force constant is 8.13 N/m. The frictional force is given by – b(dx/dt), where b = 227 g/s. Suppose that the block is pulled aside a distance 12.5 cm and released. (a) Calculate the time interval required for the amplitude to fall to one-third of its initial value. (b) How many oscillations are made by the block in this time?
