MATH PROBLEM FROM CHINA | If a ship had 26 sheep and 10 goats onboard, how old is the ship's captain?

A passenger on a large ship sailing in a quiet sea hangs a ball from the ceiling of her cabin by means of a long thread. Whenever the ship accelerates , she notes that the pendulum ball lags behind the point of suspension and so the pendulum no longer hangs vertically. How large is the ship's acceleration when teh pendulum stands at an angle of 5^(@) to teh vertical?

A man standing on the top of a light house sees a ship approaching the seashore at an angle of depression of 22^circ . After the ship has travelled 100 meters more towards the sea shore, he sees it at an angle of depression of 31^circ .The ship stopes there. a) Draw a rough-sketch. b) How far is the ship from the light house. c) Find the height of the light house. (tan 22^circ =0.4, tan 31^circ =0.6)

From the top of a lighthouse , an observer looks at a ship and finds the angle of depression to be 30^@ . If the height of the lighthouse is 100m, then find how far is that ship from the lighthouse.

From a top of a lighthouse, an observer looks at the ship and find the angle of depression to be 45^(@) . If the height of the lighthouse is 1000m , then how far is that ship from the lighthouse.
