A block weighing 4 kg is supported by a spring with a constant of k = 128 N/m and a dashpot with a coefficient of viscous damping of c = 0.6 N·s/m. The block is in equilibrium when it is struck from below by a hammer that imparts to the block an upward velocity of 0.4 m/s.
Determine the maximum upward displacement of the block from equilibrium after two cycles.
The maximum upward displacement is _ mm.
