A shoreline observation post is located on a cliff such that the observer is 300 feet above sea level. The observer spots a ship approaching the shore and the ship is traveling at a constant speed. To input your angle measures in degrees, use the functions sind (5), cosd (5) and tand (5), instead of sin (5), cos (5) and tan (5). Angle of depression a. When the observer initially spots the ship, the angle of depression for the observer's vision is 7 degrees. At this point in time, how far is the ship from the shore? feet Preview b. After watching the ship for 52 seconds, the angle of depression for the observer's vision is 13 degrees. At this point in time, how far is the ship from the shore? feet Preview c. What is the ship's constant speed (in ft/sec)? Note: Velocity has direction, but speed is the absolute value of velocity and so speed is non- negative. ft/sec Preview d. If the ship continues traveling at this constant speed, how many seconds after the observer initially spotted the ship will the ship crash into the shore? sec Preview
