An aluminum block weighing 40 lbs is connected horizontally to rigid walls on both sides by identical springs of stiffness k (= 40 lb/in). It was initially at rest. The block subjected to a horizontal impulse of magnitude 50 Ib-sec. What will be the maximum velocity of the block and how long will it take to reach that maximum velocity? k k M Po
