The elastic cord has an unstretched length l0 = 1.5 ft and a stiffness k = 12 lb/ft. It is attached to a fixed point at A and a block at B, which has a weight of W = 2.2 lb. The block is released from the rest from the position shown. After leaving the guide, it is launched onto the smooth horizontal plane. (Figure 1) (A) Determine its speed when it reaches point C after it slides along the smooth guide. Express your answer to three significant figures and include the appropriate units.   (B) Will the angular momentum of the block about point A be conserved after it passes point C? yes or no.    (C)  Calculate the magnitude of the angular momentum of the block about point A, at any instant after it passes point C. Express your answer using three significant figures.
