6.
At a given instant in an airplane race, airplane A is flying horizontally in a straight line,
and its speed is being increased at the rate of 8 m/s. Airplane B is flying at the same
altitude as airplane A and, as it rounds a pylon, is following a circular path of 300-m
radius. Knowing that at the given instant the speed of B is being decreased at the rate of
4 m/s, determine, for the positions shown, (a) the velocity of B relative to A, (b) the
acceleration of B relative to A.
