1. The problem statement, all variables and given/known data A 735N mountain climber is rappelling down the face of a vertical cliff as shown in the diagram. If the rope makes an angle of 12deg with the vertical face, what is the tension in the rope? 2. Relevant equations Fnet=ma trig functions Ff=uFN 3. The attempt at a solution I seperated force into x and y components X --- FN-Tx=0 therefore FN=Tx Y ---- Ff+Ty-mg=0 Ff=uFN=uTx uTx+Ty-mg=0 uTcos78+Tsin78-mg=0 I need help from here...the answer in the book says 751N, so i don't know...maybe i setup my net force equation wrong?
