Arlene is to walk across a “high wire” strung horizontally between two buildings 10.0 m apart. The sag in the rope when she is at the midpoint is 10.0º as shown in the figure below. If her mass is 50.0 kg, what is the tension in the rope at this point?
2 T sin(Θ) = m g
2 * T * sin(10.0º) = 50.0 * 9.81
answer is in Newtons
