The drag force that resists the motion of a car traveling at 80 km h^- 1 is 300 N. A. What power is required to keep the car traveling at that speed?

B. If the efficiency of the engine is 60%, what is the power of the engine?

Answer///air resistance,drag;

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.
