Two ships, A and B, leave port at the same time. Ship A travels northwest at 20 knots and ship B travels at 28 knots in a direction 34°
west of south. (1 knot = 1 nautical mile per hour; see Appendix D.) What are (a) the magnitude (in knots) and (b) direction (measured
relative to east) of the velocity of ship A relative to B? (c) After how many hours will the ships be 190 nautical miles apart? (d) What will
be the bearing of B (the direction of the position of B) relative to A at that time? (For your angles, takes east to be the positive x-
direction, and north of east to be a positive angle. The angles are measured from -180 degrees to 180 degrees.)
