In a supermarket, a person pushes his 16-kg shopping cart with a force of magnitude 56 N and a direction of 30 ° below the horizontal. When passing through the candy aisle, he decides not to stop i because he is on a diet, so he travels a distance of 10 m at a speed that we can consider constant. What work did the friction do as the person passed through the candy aisle? a) W = -484.9742 J. b) W = -560 J. c) W = 0 J. d) W = -280 J. %3D

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 0.9 m, (b) 1.0 to 2.0 m, and (c) 2.0 to 3.8 m. (Note: In the last interval the force component is negative, so the work is negative.)
