At a certain instant after jumping from the airplane A, a skydiver B is in the position shown and has reached a terminal (constant) speed v_B = 50 m/s. The airplane has the same constant speed v_A = 50 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρ_A = 2000 m. (a) Determine the velocity and acceleration of the airplane relative to the skydiver. (b) Determine the time rate of change of the speed v_r of the airplane and the radius of curvature r of its path, both as observed by the nonrotating skydiver.
