Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_138

5/138 The air transport B is flying with a constant speed of 480 mi/hr in a horizontal arc of 9-mi radius. When B reaches the position shown, aircraft A, flying southwest at a constant speed of 360 mi/hr, crosses the radial line from B to the center of curvature C of its path. Write the vector expression, using the x-y axes attached to B, for the velocity of A as measured by an observer in and turning with B.
