A bicycle wheel of radius 0.36 m and mass 3.2 kg is set spinning at 4.00 rev/s. A very light bolt is attached to extend the axle in length, and a string is attached to the axle at a distance of 0.10 m from the wheel.
 
  Initially the axle of the spinning wheel is horizontal, and the wheel is suspended only from the string. We can ignore the mass of the axle and spokes. At what rate will the wheel process about the vertical?
  A) 2.9 rpm
  B) 1.9 rpm
  C) 18 rpm
  D) 0.30 rpm
  E) 0.77 rpm

Question 2

Three solid, uniform, cylindrical flywheels, each of mass 65.0 kg and radius 1.47 m rotate independently around a common axis.
 
  Two of the flywheels rotate in one direction at the other rotates in the opposite direction at 3.42 rad/s. Calculate the magnitude of the net angular momentum of the system.
  A) 298 kg  m2/s
  B) 778 kg  m2/s
  C) 257 kg  m2/s
  D) 222 kg  m2/s
