Two masses, m₁ = 2.28 kg and m₂ = 1.79 kg, are connected by a light rope hanging over a pulley. Mass m₁ is on the left hand side of the pulley and mass m₂ is on the right hand side. The pulley is a uniform disk with

mass m₂ = 0.730 kg and radius rp = 24.0 cm.

Part 1)

What is the moment of inertia of the pulley?

Part 2)

What is the acceleration of mass m₁? If this mass moves downwards your answer should be positive.

Part 3)

What are the torques on the pulley due to mass m₁ (71). and due to mass m₂ (72)? For this question a torque directed out of the page is considered positive.

7₁ =

72 =
