Suppose the boat A is moving relative to the water with a velocity of 6 m/s due east and boat B is moving with a velocity of 12 m/s due west. Assume that observers on both boats use reference frames in which the x direction points east. According to the Galilean veloc- ity transformation equations, what is the velocity of boat A relative to boat B. (Hint: Draw a picture. Be sure to define which object corresponds to which frame.)
