an adventurous archeologist crosses between two rocks cliffs, with a ranging river far below, 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 x 10⁴N, and our heros mass is 81.6 kg.
a. if the angle that the rope makes with the cliff is 75°find the tension in the rope.
b. What is the smallest value the angle can have if the rope is not to break?
