At a given instant in an airplane race, airplane A is flying horizontally in a straight line, and its speed is being increased at a rate of 6 m/s^2 . Airplane B is flying at the same altitude as airplane A and, as it rounds a pylon, is following a circular path of 200-m radius. Knowing that at the given instant the speed of B is being decreased at the rate of 2 m/s^2 , determine, for the positions shown, (a) velocity of B relative to A, and (b) acceleration of B relative to A.
