Homework Statement
A climber of mass 64.8 kg is rappelling down a cliff, but has momentarily paused. She stands with her feet pressed against the icy, frictionless rock face and her body horizontal. A rope of negligible mass is attached to her near her waist, 1.04 m horizontally from the rock face. There is 5.25 m of rope between her waist and where the rope is attached to a chock in the face of the vertical wall she is descending. Calculate the tension in the rope.
Homework Equations
FL + (-mg cos theta) = 0
t + (-mg) = ma
The Attempt at a Solution
I think that I have to find the angle by using cos = adj./hyp. but that answer comes out very small and doesn't seem correct
or should I find the acceleration first and use t + (-mg) = ma
