Answer Key : (8) -

According to the graph the acceleration  varies linearly with the coordinate . We may write , where  is the slope of the graph.

From the graph

The force on the brick is in the positive -direction and according to Newton’s second law, its magnitude is given by

If  is the final coordinate, the work done by the force is
