You are using a small telescope to view two closely spaced light bulbs located a mile away. Each light bulb is emitting blue light. At this distance, the light bulbs are still too close together for you to distinguish them as separate bulbs. If they were emitting red light instead, would you have a better or worse chance of distinguishing them as separate bulbs?

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

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.
