When expressing angular kinematic quantities like angular velocity, we sometimes use a curved arrow and a scalar quantity to explicitly show the plane in which the object is rotating. Alternatively, the same information can be conveyed by using a vector quantity. This and the next question test your ability to express the same information in these two alternative ways. Y W X The figure shows a rotating rigid body. Rotation is within the xy-plane. The angular velocity along the indicated direction on the figure is w = +8 rad/s. The axes belong to a right-handed frame. Find the vector angular velocity . Coding note: i, j, k are coded as ihat, jhat, khat. @ = rad/s
