Plane A in Figure Q1 is flying along a straight-line path at velocity of 140 m/s, whereas plane B is flying at 110 m/s along a circular path having a radius of 1 km and slowing down at a rate of 40 m/s². If plane A is accelerating at 15 m/s², determine at that instant shown: a) velocity of plane B relative to plane A acceleration of plane B relative to plane A b) B Figure Q1 1 km
