14-41. A 2-lb block rests on the smooth semicylindrical surface. An elastic cord having a stiffness k = 2 lb/ft is attached to the block at B and to the base of the semicylinder at point C. If the block is released from rest at A (0 = 0°), determine the unstretched length of the cord so the block begins to leave the semicylinder at the instant 0 = 45°. Neglect the size of the block. k = 2 lb/ft 1.5 fí
