An adventurous archaeologist crosses between two rock cliffs by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle o o rope. The rope will break if the tension in the roe exceeds 2.5x104 N. The mass o archaeologist is 90 kg. a) If the angle from the horizontal is 10°, what is the tension in the rope? b) What is the smallest angle from the horizontal that the rope can have for tne rop not break?
