Question

10. A shoreline observation post is located on a cliff such that the observer is 310 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 4.8° a. Draw a diagram of the situation and label each known and unknown quantity measure b. How far out to sea was the ship when it was first spotted? c. After watching the ship for 47 seconds, the angle of depression was 5.9°. 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? d.
