An airplane is flying straight and level at a speed vo = 150 mph and with a constant time rate of increase of speed v' = 20 ft/s^2, when it starts to climb along a circular path with a radius of curvature p = 2000 ft. The airplane maintains v' constant for about 30s. Determine the acceleration of the airplane 25s after the start of the climb and express the result in the Cartersian component system shown.
