A telephone lineman is told to stretch the wire between two poles so the poles exert an 800Nforce on the wire. As the lineman does not have a scale to measure forces, he decides to measure the speed of a pulse created in the wire when he hits it with a wrench. The pulse travels 60m from one pole to the other and back again in 2.6s. The 60m wire has a mass of 15kg. a. Should the wire be tightened or loosened?b. Should the wire be tightened or loosened?
