A mountain climber, in the process of crossing among two cliffs by a rope, pauses to rest. She weighs 555 N. She is closer to the left cliff than to 2 the right cliff, with the result that the tensions in the left and the right sides of the rope are not the same. Discover the tensions in the rope to the left and to the right of the mountain climber. (Hint: Notice that the climber's and the rope's accelerations are zero! Carefully draw a free body diagram for the point on the rope above the climber and apply Newton's second law. You will require considering both the x and the y axis to solve for both tensions.)
