Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_139

5/139 For the conditions of Prob. 5/138, obtain the vector expression for the acceleration which aircraft A appears to have to an observer in and turning with aircraft B, to which axes x-y are attached. Conditions of Prob. 5/138 (Reference): The air transport B is flying with a constant speed of \( 480 \text{ mi/hr} \) in a horizontal arc of \( 9\text{-mi} \) radius. When B reaches the position shown, aircraft A, flying southwest at a constant speed of \( 360 \text{ mi/hr} \), crosses the radial line from B to the center of curvature C of its path. (The diagram shows aircraft A at a distance of \( 5\text{ mi} \) from B along the radial line \( BC \), and the coordinate axes \( x-y \) are attached to B such that \( x \) is in the radial direction towards \( C \) and \( y \) is tangential to the path in the direction of motion.)
