Question 1173048
.
<pre>

(a)  To find average velocity, divide the traveled distance by the travel time.


     The vector is directed North.



(b)  To find the acceleration, find the difference of velocities and divide it by the elapsed time.



(c)  The "run" in this case is NOT 4.0 m/s.    It is 4.0 seconds,   INSTEAD.


     To find the magnitude of the acceleration, divide the rise of the velocity by the elapsed time.

It is very crude error, &nbsp;which you made in part &nbsp;(c) &nbsp;saying that &nbsp;"the run is &nbsp;4 &nbsp;m/s".

So crude, &nbsp;that an expert &nbsp;MOMENTARILY &nbsp;sees that you can not read and understand correctly the kinematic plots.


By the way, &nbsp;the ability &nbsp;"to read" &nbsp;and correctly interpret &nbsp;plots &nbsp;"distance versus time", &nbsp;"velocity versus time", 

"acceleration versus time" &nbsp;is one of important skills in &nbsp;Kinematic as a part of &nbsp;Mechanics.


I am telling it to you in order for you know how important it is and avoid such mistakes in the future.

If you have a possibility to exercise more in reading such plots, &nbsp;do not miss it &nbsp;(!)



Good luck &nbsp;(!)
