Help...A 33.7 kg rock is on the edge of an 182 m cliff. The acceleration of gravity is 9.8 m/s^2
What potential energy does the rock possess relative to the base of the cliff?
Answer in units of J.

The rock falls from the cliff. What is its kinetic energy just before it strikes the ground?
Answer in units of J

What speed does the rock have as it strikes
the ground?
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. 

Because they're in different places for this the temperature varies.
