A Mass (M₁ = 5

A mass (M₁ = 5.0 kg) is connected by a light cord to a mass (M₂ = 4.0 kg) which slides on a smooth surface, as shown in the figure. The pulley (radius = 0.20 m) rotates about a frictionless axle. The acceleration of M₂ is 3.5 m/s². What is the moment of inertia of the pulley?

A) 0.29 kg⋅m²
B) 0.42 kg⋅m²
C) 0.20 kg⋅m²
D) 0.62 kg⋅m²
E) 0.60 kg⋅m²
