A 200 kg object is initially at rest on a horizontal frictionless surface. At time t = 0, a horizontal force of 100 N is applied to the object for 1 s and
then removed. Which of the following is correct about the object's
motion at the time t = 2 s?
O It is moving at a constant speed
It is moving with decreasing speed
O It is moving with decreasing speed
O It is moving with decreasing acceleration

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. 

Wow good luck with that answer

Give me some answer choices and i will be happy to
