The force component along the displacement varies with the magnitude of the displacement, as shown in the graph. Find the work done by the force in the interval from
(a) 0 to 0.1 m,
(b) 2.0 to 2.0 m, and
(c) 2.0 to 4.0 m. (Note: In the last interval the force component is negative, so the work is negative. f=8.0 N)
