When the angle given is with respect to the vertical (y-axis).

Well, what do

If the average velocity of an abject is zero in some time interval, what can u say about the displacement of the object for that interval?

of course you must have some clue or idea.i hv no idea

can you draw two vectors that have no common component? What can you say about them? hint: look at angles.

Q2: What is the definition of velocity (speed and velocity is not the same), and average velocity?
