7. ### Determine the work done to move the particle from x=0 to x = 13.3 m graphically, by determining the area under the Fx versus x graph.?

area is two triangles and a rectangle, see below. 1.  area = (1/2)(430)3.4 2.  area = 430(6.1–3.4) 3.  area = (1/2)(430)(13.3–6.1) add them up to get total W = 430(1.7+2.7+3.6) = 3440 J
