Solve the all parts of following question:
Question: 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 2.00 x 104 N. Our heroes mass is 70.0kg.
Part A: If the angle is 13.0o, find the tension in the rope. Start with a free-body diagram of the archaeologist.
Part B: What is the smallest value the angle can have if the rope is not to break?
