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 (See the figure). The rope will break if the tension in it exceeds 2.50×104 N . Our hero’s mass is 90.0 kg A.If the angle θ is 15.0 ∘, find the tension in the rope. Start with a free-body diagram of the archaeologist. B.What is the smallest value the...
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 (See the figure). The rope will break if the tension in it exceeds 3.50×104 N . Our hero’s mass is 70.0 kg . A)If the angle θ is 12.0 ∘, find the tension in the rope. Start with a free-body diagram of the archaeologist. b)What is the smallest value...
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. (Figure 1) The rope will break if the tension in it exceeds 3.00×104 N. Our hero’s mass is 70.0 kg. If the angle θ is 15.0 ∘, Part A find the tension in the rope. Part B What is the smallest value the angle θ can have if the...
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 middleof the rope (Figure 1) . The rope will break if the tension in it exceeds 2.45×104N , and our hero's mass is 89.2kg .(A) If the angle between the rope and the horizontal is theta = 11.7^circ, find the tension in the rope.(B) What is the smallest value the angle theta can have if...
The 185-lb rock climber is lowered over the edge of the cliff by his two companions, who together exert a horizontal pull T of 77 lb on the rope. Compute the coefficient of friction between the rope and the rock. 533 90° Answer:
