SUMMARY
The problem involves calculating the tension in a rope when a person, Arlene, is midway across a high wire strung between two buildings, with a distance of 10.0 meters between them and a sag of 10.0 meters. Given Arlene's mass of 47.0 kg, the correct approach to find the tension involves using the equilibrium of forces, specifically the equations Tension = ma and F = ma. By summing the vertical forces to solve for the vertical component of tension and then using the angle of the rope, one can determine the total tension in the rope.
