A sandal is dropped from the top of a 15.0-m-high mast on a ship moving at 1.75 m/s due south. Calculate the velocity of the sandal when it hits the deck of the ship: 

(a) Relative to the ship and

(b) Relative to a stationary observer on shore.

(c) Discuss how the answers give a consistent result for the position at which the sandal hits the deck.
