3. The bar shown rotates about the z-axis. Find the velocity
and accleration of point P for the instant when the
angular aceleration is 4 rad/s² and angular velocity is 1.5
rad/s, both in the directions shown. Give your answers in
terms of the given Cartesian coordinates.
Note: This problem is trying to fool you. The
position vector re must be normal to the axis of
rotation, which is not from point O.
