It's bouncing off a y-z plane. Just bounce a ball off a vertical wall, and see which components reverse and which components remain the same. Only the component normal to the plane reverses.

how the velocity vector drawn with red color can be broken into x-y-z components ?It's bouncing off a y-z plane. Just bounce a ball off a vertical wall, and see which components reverse and which components remain the same. Only the component normal to the plane reverses.

Chet

how you came to know that?It's bouncing off a y-z plane.

You can always resolve a vector into components.how the velocity vector drawn with red color can be broken into x-y-z components ?

You can see in the figure that the wall that it bounces off is parallel to the y-z plane.how you came to know that?

i know how to resolve vectors but only in 2 dimensions.You can always resolve a vector into components.

Well, it can be done in 3 dimensions too.i know how to resolve vectors but only in 2 dimensions.

Yes. In 3D space, all vectors can be resolved into combinations of 3 linearly independent components.can all vectors be resolved in 3 dimensions?

but only vectors which are in 3d ,for example this kind of vector (in the image below) can only be resolved in 2d i.e only with two perpendicular component.right?Yes. In 3D space, all vectors can be resolved into combinations of 3 linearly independent components.

All that means is that the component out of the paper is zero.but only vectors which are in 3d ,for example this kind of vector (in the image below) can only be resolved in 2d i.e only with two perpendicular component.right?

ok if any vector is coming out of page ,what it's x component would be?i can only imagine it in y z plane.All that means is that the component out of the paper is zero.

If the vector is through the origin, then you drop a normal from its tip to each of the three coordinate axes to get its x, y, and z components.ok if any vector is coming out of page ,what it's x component would be?i can only imagine it in y z plane.
