A wagon with mass 4.5 kg is dragged along a flat surface with constant velocity by a force of 73 N at an angle of 27 degrees above the horizontal. How big is the normal force acting on the wagon? How big is the frictional force acting on the wagon?

The answer should be a.

The answer would be a

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.
