A Wheel (Radius = 0

A wheel (radius = 0.20 m) is mounted on a frictionless,horizontal axis.A light cord wrapped around the wheel supports a 0.50-kg object,as shown in the figure.When released from rest the object falls with a downward acceleration of 5.0 m/s².What is the moment of inertia of the wheel?

A) 0.023 kg⋅m²
B) 0.027 kg⋅m²
C) 0.016 kg⋅m²
D) 0.019 kg⋅m²
E) 0.032 kg⋅m²
