Samochód ruszył ruchem jednostajnie przyspieszonym, z przyspieszeniem a= 3 m/s2. w ostatniej sekundzie tego ruchu przebył drogę s = 16,5 m. oblicz, jaka była cała droga, na której samochód przyspieszał i jak długo trwał ten ruch

For me a person with a phd and who knows what there talking about.i know the chances of a radiation leak is low but if it does the area within a 96.3 mile radius would be unusable because of contamination

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. 

120v is the answer i am positive tell me if this was correct
