According to the graph the acceleration From the graph
The force on the brick is in the positive
If
|
varies linearly with the coordinate 
. We may write 
, where 
is the slope of the graph.
-direction and according to Newton’s second law, its magnitude is given by
is the final coordinate, the work done by the force is
