shoreline observation post is located on a cliff such that the observer is 407 feet above sea level. When initially spotted, the angle of depression (the angle at which an observer needs to look down) from the observation post to an approaching ship was 3.4 ∘. How far out to sea was the ship when it was first spotted? After watching the ship for 34 seconds, the angel of depression was 36.5∘. Assuming the ship was moving at a constant rate, estimate the ship’s velocity. If the ship were to continue on its course at the same velocity, how much time from the second reading will elapse before the ship crashes into the shore?

Question
A shoreline observation post is located on a cliff such that the observer is 407 feet above sea level. When initially spotted, the angle of depression (the angle at which an observer needs to look down) from the observation post to an approaching ship was 3.4 ∘.
How far out to sea was the ship when it was first spotted?
After watching the ship for 34 seconds, the angel of depression was 36.5∘. Assuming the ship was moving at a constant rate, estimate the ship’s velocity.
If the ship were to continue on its course at the same velocity, how much time from the second reading will elapse before the ship crashes into the shore?
