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 2.95EE4 (2.95 x 10^4) , and our hero's mass is 93.8 .

A. If the angle between the rope and the horizontal is = 11.0, find the tension in the rope.

B. What is the smallest value the angle can have if the rope is not to break?

The following answers are incorrect:

A. 4817.6 N

B. 1.78 degrees
