A Wheel (Radius = 0

question 21

Multiple Choice

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 rotational 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
