The heading of an object is the angle, measured clockwise from due north, to the vector representing the intended path of the object. Example 4 A plane is flying with an airspeed of 185 miles per hour and a heading of 12o* . The wind currents are running at a constant 32 miles per hour at 165 clockwise from due north Find the true course and ground speed of the plane?

The angular momentum vector of a precessing gyroscope sweeps out a cone as shown in the figure below. The angular speed of the tip of the angular momentum vector, called its precessional frequency, is given by w, = t/L, where t is the magnitude of the torque on the gyroscope and L is the magnitude of its angular momentum. In the motion called precession of the equinoxes, the Earth's axis of rotation precesses about the perpendicular to its orbital plane...
