A rope of length L = 1.2 m is attached to a support at point C. A person of mass 100 kg sits on a ledge at position A holding the other end of the rope so that it is horizontal and taut, as shown. The person then drops off the ledge and swings down on the rope toward position B on a lower ledge where an object of mass 63 kg is at rest. At position B the person grabs hold of the object and simultaneously lets go of the rope. The person and the object then land together in the lake at point D, which is a vertical distance L below position B. Air resistance and the mass of the rope are negligible. Determine the total horizontal displacement x of the person from position A until the person and object land in the water at point D.
