b. Calculate the tension in the rope?
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?
An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. When the craft was stationary, the tension in the cable was 6000 N. When the craft was lowered or raised at a steady rate, the motion through the water added an 1800 N drag force.a. What was the tension in the cable when the craft was being lowered to the seafloor?b. What was the tension in the cable when the craft was being raised from the seafloor?
