Two ships A and B are moving with constant speeds vA = 12 m/s and vg = 25 m/s, respectively, along straight intersecting courses. The navigator of ship B notes the time rates of change of the separation distancer between the ships and the bearing angle 0. If r= 90 m and e = 102, what does the navigator measure for i, ř, ð and Ö? Check that i – rở = 0 and rõ + 2rð = 0. 61 Answers: m/s m/s? = i rad/s rad/s2
