A girl weighing 25kg while dancing exerts a force of 250N on the floor. Her Feet cover an area of 80 cm2 on the floor. The pressure exerted by the girl on the floor is .
a. 2000N/cm2
b. 500000N/cm2
c. 200000N/cm2
d. 2000N/m2

When is this

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. 

Because they're in different places for this the temperature varies.
