Two ships A and B are moving with constant speeds v = 30 m/s and vg = 18 m/s, respectively, along straight intersecting courses. The navigator of ship B notes the time rates of change of the separation distance r between the ships and the bearing angle 8. If r = 117 m and 8 = 110°, what does the navigator measure for i, ", ở and 0? Check that - rở = 0 and ro + 2r0 = 0. 50
