15-109. The elastic cord has an unstretched length lo = 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 2 lb. If the block is released from rest from the position shown, determine its speed when it reaches point C after it slides along the smooth guide. After leaving the guide, it is launched onto the smooth horizontal plane. Determine if the cord becomes unstretched. Also, calculate the angular momentum of the block about point A, at any instant after it passes point C. 4 ft- ва 3 ft k = 12 lb/ft
