A student performs an experiment with a uniform solid disk of mass \(M = 2.0 \text{ kg}\) and radius \(R = 0.5 \text{ m}\) that is mounted on a fixed, frictionless horizontal axle. The student applies a constant net torque to the disk, causing it to accelerate from rest. The angular velocity \(\omega\) of the disk as a function of time \(t\) is recorded and displayed in the graph shown. What is the magnitude of the net torque applied to the disk?
