How Is the X-Component of a Vector Determined Using Sine?

[stunning]

pleasezzzzzzzz help me ...

in what circumstances is the x-component of a vector given by magnitude of a vector times the sine of its direction angle?

 

[Doc Al]

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?

Well, what do you think?

i hv no idea

 

[Sourabh N]

what do you mean by component of vector A along the direction of vector B?

i hv no idea

of course you must have some clue or 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?
