One end of a 14 m long wire having a total mass of .8000 kg is fastened to a fixed support in the ceiling, and a 7.50 kg object is hung from the other end. If the wire is struck a transverse blow at one end, how much time does the pulse take to reach the other end? neglect the variation in tension along the length of the wire.
