2. (15 points) Consider that a rigid body with unit vectors b move with respect to the inertial frame . At the initial time, = b, = b and 3 = 63. The final orientation of with respect to is given by: u = 3 - 2 + 3 0 = -45 (a) Sketch in 3D including the direction of the rotation given by 0. (b) Compute the final DCM.
