A knife is dropped from the top of a 10.0 meter high Mast on a ship moving at 1.73 meters per second due south. Calculate the velocity of the night relative to the ship when it hits the deck of the ship. Calculate the velocity of the knife relative to the stationary Observer on the shore. Discuss how the answers give a consistent result for the position at which the knife hits the deck.
