A flight simulator is used to train pilots on how to recognize spatial disorientation. It has four degrees of freedom and can rotate around a planetary axis, as well as in yaw, pitch, and roll. The pilot is seated so that her head B is located at r = (2 ft) i + (1 ft) j with respect to the center of the cab A. Knowing that the cab is rotating about the planetary axis with a constant angular velocity of 20 rpm counterclockwise as seen from above, and pitches with a constant angular velocity of +3k rad/s, determine (a) the velocity of the pilot’s head, (b) the angular acceleration of the cab, (c) the acceleration of the pilot’s head.
