In the question, you just gave a complete and detailed 
description of the plane's velocity vector:
       4,000/16  meters/second , heading 35 degrees .
You might want to simplify the speed and make it a unit rate,
but otherwise, it's perfect.
         250 meters/second, heading 35 degrees .
        
             
        
        
        
The change in angular displacement as a function of time is the definition given for angular velocity, this is mathematically described as

Here,
 = Angular displacement
 = Angular displacement
t = time 
The angular velocity is given as

PART A) The angular velocity in SI Units will be,


PART B) From our first equation we can rearrange to find the angular displacement then

Replacing,


 
        
             
        
        
        
the answer is D cuz electricity is a conductive
 
        
             
        
        
        
<u>Answer:</u>
Yes
<u>Explanation:</u>
Average velocity is the ratio of total displacement and time taken for that displacement:

This means if displacement is zero, then average velocity will also be zero.
Displacement is zero when an object moves some distance in one direction, and then moves the same distance but in the opposite direction.
∴ As it is possible for displacement to be zero, it is also possible for average velocity to be zero.
