Acement block accidentally falls from rest from the ledge of a 53.0-m-high building. when the block is 14.0 m above the ground, a man, 2.00 m tall, looks up and notices that the block is directly above him. how much time, at most, does the man have to get out of the way?

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.
