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 of the rope. The rope will break if the tension in it exceeds 3.00×104 N. Our hero’s mass is 85.0 kg. Part A: If the angle θ is 13.0 ∘, find the tension in the rope (answer in form T= ? N. Part B: What is the smallest value the angle θ can have if the rope is not to break?
