8) Calculate the kinetic energy of a truck that has a mass of 6100 kg and is moving at 55 m/s.

9,226,250 J

Explanation:

The kinetic energy of an object can be found by using the formula

v is the velocity

m is the mass

From the question we have

We have the final answer as

9,226,250 J

Hope this helps you

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.
