A sailor drops a pair of binoculars from the “crow’s nest” at the top of a sailing ship’smast. When the ship is at rest, the binoculars land at the base of the mast. If the shipis moving forward with constant velocity, and air resistance can be ignored, do thebinoculars land in front of the mast (toward the front of the ship), at the base of themast, or behind the mast (toward the rear of the ship)? Explain.
