An object starts at x-0m. A variable force is then applied to the object that is given by F1-75x, where F1 is in N. When the object reaches x-2.0 m, a variable force F₂-- 75x, where F2 in in N, acts on the object until the object reaches x-4.0 m. Carefully draw a graph the of variable forces versus the displacement of the object. Use your graph to determine the work done on the object as it moves from x-0 to 4.0 m. i
