A fisherman has caught a very large, 5.0 kg fish from a dock that is 2.0 m above the water. He is using a lightweight fishing line that will break under a tension of 60N or more. He is eager to get the fish to the dock in the shortest possible time. If the fish is at rest at the water's surface, what's the least amount of time in which the fisherman can raise the fish to the dock without losing it? Express your answer with the appropriate units.
