Asatellite 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?

Explanation:

As we know that central bus has moment of inertia as

also the solar array has moment of inertia given as

total moment of inertia of the satellite is given as

now the rotation rate is given as

now the angular acceleration is given as

now torque is given as

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
