A 2.5-lb block is supported as shown by a spring of constant k = 2 lb/in. that can act in tension or compression. The block is in its equilibrium position when it is struck from below by a hammer that imparts to the block an upward velocity of 90 in./s. Determine the position, velocity, and acceleration of the block 0.85 s after it has been struck by the hammer. (Round the final answers to two decimal places. A 177

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.
