5.60 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
(Fig. P5.60). The rope will break if the tension in it exceeds
2.50 x 10 N, and our hero's mass is 90.0 kg. (a) If the angle
is 10.0°, what is the tension in the rope? (b) What is the smallest
value 0 can have if the rope is not to break?
