A fish weighing 25 lb is caught and hauled onto the boat. (a) Compare the tension in the fishing line when the fish is brought up vertically at a constant speed to the tension when the fish is held vertically at rest for the picture-taking ceremony on the wharf. In which case is the tension largest: (1) When the fish is moving up; (2) when the fish is being held steady; or (3) the tension is the same in both situations (b) Calculate the tension in the fishing line.
