A racket ball is struck in such a way that it leaves the racket with a speed of 4.89 m/s in the horizontal direction. When the ball hits the court, it is a horizontal distance of 1.97 m from the racket. Find the height of the racket ball when it left the racket.
Express your answer using three significant figures and include the appropriate units

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. 

Iwould say the answer is d

i hope i
