Explanation / Answer

Work done will be equal to the area under F-d graph.

A)W = area of triangle + area of rect

W = 1/2 x 2 x 2 + 1 x 2 = 4 N-m

W = 4.00 J

B)since, F = 0 N for x = 3 to 4 m

W = 0.00 J

C)W = 1/2 x 2 x -1 + 0 = -1 J

W = -1.00 J

D)from x = 0 to 7

W = 4 + 0 - 1 = 3 J

Hence, W = 3.00 J
