The drop hammer H has a weight { W }_{ H } and falls from rest h onto a forged anvil plate P that has a weight { W }_{ P } . The plate is mounted on a set of springs that have a combined stiffness { k }_{ T } . Determine (a) the velocity of P and H just after collision and (b) the maximum compression in the springs caused by the impact. The coefficient of restitution between the hammer and the plate is e. Neglect friction along the vertical guideposts A and B. Given: { W }_{ H } = 900 lb , { k }_{ T } = 500 lb/ft , { W }_{ P } = 500 lb , g = { 32.2ft/s }^{ 2 } , h = 3 ft , e = 0.6
