A box of mass m is at rest on a horizontal surface. Aconstant force of magnitude FA is applied and the box moves in the direction shown in the diagram below. There is friction between the box and
the horizontal surface, but the frictional force, Fr, is smaller in magnitude than FA-

A. to determine if humans can explore mars safely

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.
