the diagram below shows the situation described in the problem. the focal length of the lens is labeled f; the scale on the optical axis is in centimeters. draw the three special rays, ray 1, ray 2, and ray 3, as described in the tactics box above, and label each ray accordingly. do not draw the refracted rays.

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 vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
