A zero-momentum spin stabilized satellite has a momentum wheel spinning at 5000 rpm. The angular momentum of the wheel is 100 N-m-sec.

a) What is the spin rate of the satellite if its moment of inertia is 500 kg-m²?

b) What is the moment of inertial of the wheel?

c) If there were a problem with the wheel and it was stopped, what would be the spin rate of the satellite?

d) Assuming the problem was fixed, how long would it take to get back up to a speed of 4000 rpm applying a motor torque of 0.1 N-m?

e) What would the new spin rate of the satellite be?

Conservation of Angular Momentum A female figure skater is spinning on ice. Assume that that the surface is basically frictionless. The skater is wearing weighted bracelets as part of the costume for the performance. These weighted bracelets weight .75 kg each. The skater has a spinning routine in the middle of the performance and initially starts spinning with arms stretched wide such that the weighted bracelets are 1 m from the axis of rotation. She has an initial angular velocity...
