A horizontal clothesline is tied between 2 poles, 12 meters apart. When a mass of 5 kilograms is tied to the middle of the clothesline, it sags a distance of 1 meters. What is the magnitude of the tension on the ends of the clothesline?

A constant force moves an object along a straight line from point (10, 2, -6) to point (10, 5, -10).
Find the work done if the distance is measured in meters and the magnitude of the force is measured in newtons.
