2. A loop of wire of area 0.7 m is moving into a 0.9 T magnetic field. If it takes 5 seconds for the loop to move from completely outside the field to completely inside the
field, what emf is produced?

As newton's first law states a object in motion stays in motion

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.
