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

oh thank u so much...............

can ny 1 help me with these questions???
If the component of vector A along the direction of vector B is zero, what can u about the two vectors?

Q:2
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?
