In Prob. 19.12, determine the position, velocity, and acceleration of the block 0.90 s after it has been struck by the hammer.Prob. 19.123-lb block is supported as shown by a spring of constant k = 2 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 90 in./s. Determine
(a) the time required for the block to move 3 in. upward,
(b) the corresponding velocity and acceleration of the block.
