An 8-lb block is supported as shown by a spring of constant k = 3.3 lb/in. which can act in tension or compression. The block is in its equilibrium position when it is struck from below by a hammer which imparts to the block an upward velocity of 65 in./s. Determine the position, velocity, and acceleration of the block 1.20 s after it has been struck by the hammer.
