A wheel (radius = 12 cm) is mounted on a frictionless, horizontal axle that is perpendicular to the wheel and passes through the center of mass of the wheel. A light cord wrapped around the wheel supports a 0.40-kg object. If released from rest with the string taut, the object is observed to fall with a downward acceleration of 3.0 m/s2 . What is the moment of inertia (of the wheel) about the given axle?
 a. 0.023 kgm2
  b. 0.013 kgm2
  c. 0.020 kgm2
  d. 0.016 kgm2
  e. 0.035 kgm2
