Asked by Kyle

A 171-N child sits on a light swing and is pulled back and held with a horizontal force of 73.5N. The magnitude of the tension force of each of the two supporting ropes is?
Answered by drwls
Let T be the single-rope tension and A be the angle from vertical

2T sinA = 73.5
2T cosA = Weight = 171

Square and add both equations

4T^2 = 73.5^2 + 171^2

Solve for T
