We decided to make an iced latte by adding ice to a 200 ml hot latte at 45 °c. the ice starts out at 0 c. how much ice do we need to add for the final drink to be 10 c? the latent heat of fusion of ice is 335 j/g. approximate the latte as water. express your answer in g, without specifying the 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.
