... Thus, while the man walks 12 feet from the stern to the prow, the boat moves back 8 feet (i.e., 8 feet away from the pier). And by the way, the man’s displacement relatively to the pier is only 12 ft − 8 ft = +4 ft. Textbook problem 8.12: (a) For constant angular acceleration α, the angular velocity ...
