John pushes a box with a constant force as shown in the graph below.
determine the work done on the box over a displacement of 8 m.
1.8 j
110 j
140 j
1.4 j

From the graph, it can be seen that the constant force that John exerted in order to move the object is 14N. Work is calculated by multiplying the force with the distance to which the object moves in parallel with the direction of the force. 
                                      Work = Force x displacement
                                      Work = (14 N) x (8 m)
                                        Work = 112 J
The closest value is 110J. Thus, the answer to this item is the second choice.
