At a given instant in an airplane A is flying horizontally in a straight line, and its speed is being increased at a rate of 6 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 200m radius. knowing that at the given instant speed of B is being decreased at the rate of 2m/s, determine for the positions shown
a) the velocity of B relative to A
b) the acceleration of B relative to A.
