Concept explainers
To find the work will it take if the rope weights 0.624 N/m.
Answer to Problem 11E
780J work will it take if the rope weights 0.624 N/m.
Explanation of Solution
Given information: A mountain climber is about to haul up a 50-m length of hanging rope.
Calculation:
The function for the force can br determined by the weight of the rope times the length of the rope that is still hanging, i.e.
Therefore, the work is given by the integral,
Hence, 780J work will it take if the rope weights 0.624 N/m.
