Question:
Two small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at w0 = 1.25 rad/s as the two telescoping booms are extended from r1 = 1.2 m to r2 = 4.5 m at a constant rate over a 2-min period. Determine the necessary thrust T for each jet as a function of time where t = 0 is the time when the telescoping action is begun. The small 10-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible.
