**1.Homework Statement**

Arlene is to walk across a high wire strung horizontally between two buildings 13.0 m apart. The sag in the rope when she is at the midpoint is 10.0°. If her mass is 50.0 kg, what is the tension in the rope at this point?

So I know:

Mass=50kg

Acceleration=0 m/s

^{2}

## Homework Equations

This is the part I need help with because I'm not exactly sure what formula to use to find tension motion. Since F=ma would just give me 0 which would be incorrect.

The only other Formula I can think of is 2cos(theta)T

_{y}=mg, but I'm not too sure if that's correct. Plus, I don't know what T

_{y}is.
