Chapter 2, Practice Problem 2/088 Two ships A and B are moving with constant speeds VA = 19 m/s and vg = 22 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 9. If r = 87 m and 9 = 108°, what does the navigator measure for *, *,0 and Ö? Check that - ro² = 0 and re+2+0 = 0. UA COD UB B 52° Answers: + = 7 = 8 = Ö = m/s m/s² rad/s rad/s²
