6. There is a long steel wire of length 3.25 m where its upper end is attached to the ceiling. At the other end, a 49.7 kg object is suspended. It is observed that it takes a transverse pulse 0.0413 s to travel from the bottom to the top of the wire. What is the mass (in kilograms) of the wire? Express your final answer in 3 decimal places.
