Two airplanes are performing at an air show. Plane A travels along the path shown and, for the instant under consideration, has a speed of 259 mi/hr that is increasing at a rate of 4.4 mi/hr every second. Meanwhile, plane B executes a vertical loop at a constant speed of 144 mi/hr. Determine the velocity and acceleration which plane B appears to have to the pilot in plane A at the instant represented. Assume r = 530 ft, = 49°, 0 = 49°. Find the velocities of A and B. Answers: VA = (i i+ i j) ft/sec Vg = ( i i+ i j) ft/sec?
