Q. An ocean liner leaves New York City and travels 19° north of east for 264 km. How far east and how far north has it gone? In other words, what are the magnitudes of components of the ship's displacement vector in the directions?
Q. In a television tube, electrons originally at rest are accelerated by a uniform electric field of magnitude 4 times 105N/C during the first 5cm of the tube's length; after that they move at essentially constant velocity another 45cm before hitting the screen. How long does it take them to travel the length of tube?
