A tightrope walker with a mass of 60.0 kg stands at the center of a rope which was initially strung horizontally between two poles. His weight causes the rope to sag symmetrically, making an angle of 4.80° with the horizontal. What is the tension in the rope? a. 359 N b.589N c. 2470 N !(i\ 3520 N T~1 2:F. _ T fJ a --- --) v 2. 5 (12:20-1:10pm) 2 T sit\..
