Question

An Atwood machine is constructed using a hoop with spokes of negligible mass. The 2.5 kg mass of the pulley is concentrated on its rim, which is a distance 20.3 cm from the axle. The mass on the right is 1.33 kg and on the left is 1.78 kg. 3.7 m 2.5 kg 20.3 cm ω 1.78 kg 1.33 kg What is the magnitude of the linear acceleration of the hanging masses?
