Chapter 5, Problem 5P
| 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 (Figure 5.39). The rope will break if the tension in it exceeds 2.50 × 103N. Our hero’s mass is 90.0 kg. (a) If the angle e is 10.0 °. fine the tension in the rope. Start with a free-body diagram of the archaeologist (b) What is tl1e smallest value the angle θ can have if t11e rope is not to break?
