The block B is suspended from a cable that is attached to the block at E, wraps around three pulleys, and is tied to the back of a truck. If the truck starts from rest when xD is zero, and moves forward with a constant acceleration of aD=2 m/s2, determine the speed of the block at the instant xD=3 m.
a. vB = 0.1715 m/s. b. vB = 1.155 m/s. c. vB = 0.594 m/s. d. vB = 0.515 m/s.
