The angular velocity W of a rotating solid body is a vector whose magnitude is the rate angular displacement (radians per second) and whose direction is that in which aright-handedscrew would advance if turned in the same direction. The position vector r of a point is the vector from the origin of coordinates to the point. Show that the velocity of any point in rotating solid body v=[W×r], relative to an origin located on the axis of rotation.
