A solid sphere of radius 25 cm is positioned at the top of an incline that makes 26◦ angle with the horizontal. This initial position of the sphere is a vertical distance 1.9 m above its position when at the bottom of the incline. The sphere is released and moves down the incline. 25 cm M µ ℓ 26◦ 1.9 m Calculate the speed of the sphere when it reaches the bottom of the incline if it rolls without slipping. The acceleration of gravity is 9.8 m/s 2 . The moment of inertia of a spherewith respect to an axis through its center is 2 5 M R2 . Answer in units of m/s.

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.
