Marc and Rick are pushing on opposite ends of the box shown above. Marc is pushing on the box with a force of 5 N. Rick is also pushing on the box with a force of 5 N. In which direction will the box move? A.
The box will move towards Marc because he is pushing with more force.
B.
The box will move up because the forces will be combined.
C.
The box will move towards Rick because he is pushing with more force.
D.
The box will not move because the forces are balanced.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
