Blocks A and B weigh 8 lb and 3 lb, respectively, and are connected by a
cord-and-pulley system and released from rest in the position shown with
the spring undeformed. Knowing that the constant of the spring is
20 lb/ft, determine (a) the velocity of block B after it has moved 6 in.,
3 lb (b) the maximum velocity of block B, (c) the maximum displacement of
block B. Ignore friction and the masses of the pulleys and spring.
