Question Statement: A satellite has a central bus with a moment of inertia of 50 kg-m^2 about its solar array rotation axis. In addition, it has two solar arrays which each have a MOI of 25 kg-m^2 about that axis. If a worst-case, 1 second thruster burn causes an impulse which increases the rotation rate of the full system about this axis by 1 degree/sec, what minimum holding torque would you recommend for each solar array drive?

Since it is for each solar array should it be 100*pi/180 or just 25*pi/180? Also Should I include a factor of safety?
