A 3-lb block is supported as shown by a spring of constant k = 2 lb/in. that can act in tension or compression. The block ist 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 (a) the time required for the block to move 3 in. upward, (b) the corresponding velocity and acceleration of the block. 0 A k m A 3-lb block is supported as shown by a spring of constant k = 2 lb/in. that can act in tension or compression.
