An observer in a lighthouse 250 feet above sea level spots a ship off the shore. if the angle of depression to the ship is 5°, how far is out is the ship?

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
