Hi there, can you walk me through each part of the problem below? Can you help me understand the necessary steps to solve each part? Please also provide a response to each prompt so I can compare with my own solutions.

I have added a few formula reference that may be needed for the problem below. (Any unknown information can be found by searching on the internet/making reasonable or general assumptions) Please don't repost work!

Practice Problem: Reaction Wheels How do satellites change their orientation? This is a requirement of most satellites and spacecraft. For example, a space telescope needs to point to its targets with high precision. Firing bursts from small rocket engines is far too crude for the task. Most spacecraft contain reaction wheels, also known as momentum wheels. They are ywheels with electric motors to spin up or slow down their rotation. When a wheel spins up in one direction, the spacecraft spins in the opposite direction. The Hubble Space Telescope is a tube 132m long with a mass of 11,100 kg. It has a reaction wheel that has a radius of 20 cm and a mass of 45 kg. The telescope turns at a maximum rate of 6 per minute (very slow). (a) Where do you ideally place the reaction wheel for maximum effect? Why? (b) How fast do you need to spin the reaction wheel to turn the telescope at its maximum rate? (c) (Optional) How many reaction wheels do you need to turn in any direction?
