A 80 kg student who can’t swim sinks to the bottom of the Olympia swimming pool after slipping. His total volume at the time of drowning is 18.1 liters. A rescuer who notices him decides to use a weightless rope to pull him out of the water from the bottom. Use Archimedes’s principle to calculate how much minimum tension (in Newtons) is required in the rope to lift the student without accelerating him in the process of uplift out of the water.
