A5.74 g charcoal sample from an ancient fire pit has a 14c activity of 60.4 disintegrations/min. a living tree has a 14c activity of 15.3 disintegrations/min per 1.00 g. the half-life of 14c is 5730 y. how old is the charcoal sample?

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.
