on earth, a block is placed on a friction less table. when a 50 n horizontal force i applied to the block, it accelerates at 4.0m/s2. suppose the block and table are set up on the moon. when a horizontal force of 25 n is applied to the block, what is the acceleration?

Wavelength = pie*69+69 with ur mom

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.
