A fixed 0.15 kg solid-disk pulley with a radius of 0.060 m is acted on by a net torque of 5.4 m�·N. What is the angular acceleration of the pulley?

My professor did a similar problem in class but it was extremely long and I must have gotten lost along the way, so now I don't know where I went wrong.
