three resistors R1 R2 and R3 are connected in a parallel and its equivalent resistance is Req considering our Req= 0.20 plus or minus 0.04 Ohm R 1 is equal to 0.40 plus or minus 0.09 ohm and r 3 is equal to 0.54 plus or minus 0.01 ohm find the resistance of R 2 error limits

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.
