A 1.53-kg bucket hangs on a rope wrapped around a pulley of mass 7.07 kg and radius 66 cm. This pulley is frictionless in its axle, and has the shape of a solid uniform disk.
 
  After the bucket has been released, (a) what is the angular acceleration of the pulley, and (b) what is the acceleration of the bucket?

Question 2

The drive chain in a bicycle is exerting a torque of 0.850 N  m to the wheel of the bicycle. You can treat the wheel as a thin uniform hoop (or ring) with a mass of 0.750 kg and a radius of 33.0 cm. What is the angular acceleration of the wheel?
 
  A) 10.4 rad/s2
  B) 20.8 rad/s2
  C) 5.20 rad/s2
  D) 3.43 rad/s2
  E) 1.06 rad/s2
