A horizontal clothesline is tied between 2 poles, 20 meters apart.
When a mass of 5 kilograms is tied to the middle of the clothesline, it sags a distance of 4 meters.
What is the magnitude of the tension on the ends of the clothesline?
[ I am not understanding the setup of the problem. If you can help will be awesome. ]
Just did it.
