When a rocket is 10 kilometers high, it is moving vertically upward at a speed of 1000 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 10 kilometers high, the angle of elevation from the observer is changing at a rate of ? radians per hour.

Step 1

To determine the rate of change of angle of elevation with respect to observer.

Step 2

**Given information: **Speed of rocket is shown below.

Step 3

Let h is the height and a is the...
