1. A 10 kg box is sliding along a smooth, frictionless surface at 3 m/s that also happens to be 2 m off the ground below. What is this box’s combined potential and kinetic energy (mechanical energy= Pe + Ke) 2. A ball is falling through the air straight down towards the ground below. The ball is 2.1 kg, is falling at 18 m/s, and happens to be 48 meters from the ground below. What is this box’s mechanical energy? (mechanical energy= Pe + Ke)

Aliquid is an answer i hope this

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.
