Two objects start at the same location at noon. One object moves due East at a rate of 5 meters per minute. The other object moves North-Northwest at exactly the same rate (so that the angle between them remains fixed at 120 degrees). At what rate is the distance between these two objects changing when they have each traveled 50 meters? 0 = 120 Enter an exact answer. The law of cosines, c2 = a +62-2 a b cos 0, may be helpful. ==
