Mastering Physics: Ch 05 HW Google Chrome session.masteringphysics.com 60670200 Physics for Science and Engineering I Spring 2016 Ch 05 HW oblem 5.56 Problem 5.56 Part A An adventurous archaeologist crosses between two rock cliffs by slowly going hand-over-hand along a rope If the angle between the rope and the horizontal is 6 11.3 find the tension in the rope. stretched between the cliffs. He stops to rest at the middle of the rope (Figure 1) The rope will break he tension in it exceeds 2.40 4 N and our hero's mass is 84.1 kg Subm My Answers Give Up Part B What s the smallest value the angle 6 can have f he rope is no to break? Figure of 1 Submit My Answers Give Up Start Pea Close Resources v previous l 8 of 25 l next Provide Feedback Continue Drill 9:19 PMExplanation / Answer
T = 2.40 * 10^4 N
m = 84.1 Kg
2*T*sin(11.3) = m*g
2*T*sin(11.3) = 84.1 * 9.8
T = 2103.1 N
For Smallest Angle, T = 2.40 * 10^4
2*T*sin() = m*g
= sin^-1[(84.1*9.8)/(2*2.4*10^4)]
= 0.98o
