1 point A horizontal force accelerates a box from rest across a horizontal surface
(friction is present) at a constant rate. The experiment is repeated, and all
conditions remain the same with the exception that the horizontal force is
doubled. What happens to the box's acceleration? *
It increases to more than double its original value.
It increases to exactly double its original value.
It increases to less than double its original value.
It increases somewhat.

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.
