A 1.5-kg block B is attached to an undeformed spring of constant k = 80 N/m and is resting on a horizontal frictionless surface when it is struck by an identical block A moving at a speed of 5 m/s. Considering successively the cases when the coefficient of restitution between the two blocks is (1) e =1, (2) e = 0, determine (a) the maximum deflection of the spring, (b) the final velocity of block A.
