Question B4 Figure QB4 shows a spacecraft which is moving through space at a constant velocity. The xyz axes are fixed to the craft. At the instant under consideration, the craft has a constant rotation of 1 radis about the z axis, the solar panels are at an angle of 30° to the z axis and is increasing at the constant rate of radis. (a) Determine the vector expression of the angular acceleration of the right hand panel. (4 marks)...
