When a rocket is 8 kilometers high, it is moving vertically upward at a speed of 900 kilometers per hour. At that instant, how fast is the angle of elevation of the rocket increasing, as seen by an observer on the ground 5 kilometers from the launching pad? ( Hint: The angle of elevation is the angle between the horizontal ground and the line of sight with respect to the rocket. ) When the rocket is 8 kilometers high, the angle of elevation from the observer changing at a rate of radians per hour.
