1.	A 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 D. Ifthe tmck starts from rest when x_(D) is zero and moves forward with a constant acceleration of a_(P)=3//2 m//s^(2), if the speed of the block at the instant x_(D)=3 m is :
